Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION Mettler-Toledo International Inc. ("Mettler-Toledo" or the "Company") is a leading global supplier of precision instruments and services. The Company manufactures weighing instruments for use in laboratory, industrial, packaging, logistics and food retailing applications. The Company also manufactures several related analytical instruments and provides automated chemistry solutions used in drug and chemical compound discovery and development. In addition, the Company manufactures metal detection and other end-of-line inspection systems used in production and packaging and provides solutions for use in certain process analytics applications. The Company's primary manufacturing facilities are located in China, Germany, Switzerland, the United Kingdom and the United States. The Company's principal executive offices are located in Columbus, Ohio and Greifensee, Switzerland. The accompanying interim consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and include all entities in which the Company has control, which are its wholly-owned subsidiaries. The interim consolidated financial statements have been prepared without audit, pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. The interim consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 . The accompanying interim consolidated financial statements reflect all adjustments which, in the opinion of management, are necessary for a fair statement of the results of the interim periods presented. Operating results for the three and nine months ended September 30, 2019 are not necessarily indicative of the results to be expected for the full year ending December 31, 2019 . The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, as well as disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. Actual results may differ from those estimates. A discussion of the Company’s critical accounting policies is included in Management’s Discussion and Analysis of Financial Condition and Results of Operations and the Notes to the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 . All intercompany transactions and balances have been eliminated.

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Trade Accounts Receivable Trade accounts receivable are recorded at the invoiced amount and do not bear interest. The allowance for doubtful accounts represents the Company’s best estimate of probable credit losses in its existing trade accounts receivable. The Company determines the allowance based upon a review of both specific accounts for collection and the age of the accounts receivable portfolio. Inventories Inventories are valued at the lower of cost or net realizable value. Cost, which includes direct materials, labor and overhead, is generally determined using the first in, first out (FIFO) method. The estimated net realizable value is based on assumptions for future demand and related pricing. Adjustments to the cost basis of the Company’s inventory are made for excess and obsolete items based on usage, orders and technological obsolescence. If actual market conditions are less favorable than those projected by management, reductions in the value of inventory may be required. Inventories consisted of the following: September 30, December 31, Raw materials and parts $ 128,371 $ 122,945 Work-in-progress 45,843 47,098 Finished goods 106,764 98,778 $ 280,978 $ 268,821 Goodwill and Other Intangible Assets Goodwill, representing the excess of purchase price over the net asset value of companies acquired, and indefinite-lived intangible assets are not amortized, but are reviewed for impairment annually in the fourth quarter, or more frequently if events or changes in circumstances indicate that an asset might be impaired. The annual evaluation for goodwill and indefinite-lived intangible assets are generally based on an assessment of qualitative and quantitative factors to determine whether it is more likely than not that the fair value of the asset is less than its carrying amount. Other intangible assets include indefinite-lived assets and assets subject to amortization. Where applicable, amortization is charged on a straight-line basis over the expected period of benefit. The straight-line method of amortization reflects an appropriate allocation of the cost of the intangible assets to earnings in proportion to the amount of economic benefits obtained by the Company in each reporting period. The Company assesses the initial acquisition of intangible assets in accordance with the provisions of ASC 805 "Business Combinations" and the continued accounting for previously recognized intangible assets and goodwill in accordance with the provisions of ASC 350 "Intangible - Goodwill and Other" and ASC 360 "Property, Plant and Equipment". Other intangible assets consisted of the following: September 30, 2019 December 31, 2018 Gross Amount Accumulated Amortization Intangibles, Net Gross Amount Accumulated Amortization Intangibles, Net Customer relationships $ 197,467 $ (56,508 ) $ 140,959 $ 197,942 $ (49,887 ) $ 148,055 Proven technology and patents 75,482 (46,076 ) 29,406 73,880 (42,750 ) 31,130 Tradenames (finite life) 4,482 (2,981 ) 1,501 4,504 (2,874 ) 1,630 Tradenames (indefinite life) 35,442 — 35,442 35,500 — 35,500 Other 5,455 (3,392 ) 2,063 3,684 (2,691 ) 993 $ 318,328 $ (108,957 ) $ 209,371 $ 315,510 $ (98,202 ) $ 217,308 The Company recognized amortization expense associated with the above intangible assets of $3.8 million and $3.6 million for the three months ended September 30, 2019 and 2018 , respectively and $11.3 million and $10.7 million for the nine months ended September 30, 2019 and 2018 , respectively.

Revenue Recognition Product revenue is recognized from contracts with customers when a customer has obtained control of a product. The Company considers control to have transferred based upon shipping terms. To the extent the Company’s arrangements have a separate performance obligation, revenue related to any post-shipment performance obligation is deferred until completed. Shipping and handling costs charged to customers are included in total net sales and the associated expense is a component of cost of sales. Certain products are also sold through indirect distribution channels whereby the distributor assumes any further obligations to the end customer. Revenue is recognized on these distributor arrangements upon transfer of control to the distributor. Contracts do not contain variable pricing arrangements that are retrospective, except for rebate programs. Rebates are estimated based on expected sales volumes and offset against revenue at the time such revenue is recognized. The Company generally maintains the right to accept or reject a product return in its terms and conditions and also maintains appropriate accruals for outstanding credits. The related provisions for estimated returns and rebates are immaterial to the consolidated financial statements. Certain of the Company’s product arrangements include separate performance obligations, primarily related to installation. Such performance obligations are accounted for separately when the deliverables have stand-alone value and the satisfaction of the undelivered performance obligations is probable and within the Company's control. The allocation of revenue between the performance obligations is based on the observable stand-alone selling prices at the time of the sale in accordance with a number of factors including service technician billing rates, time to install, and geographic location. Software is generally not considered a distinct performance obligation with the exception of a few small software applications. The Company generally does not sell software products without the related hardware instrument as the software is embedded in the product. The Company’s products typically require no significant production, modification, or customization of the hardware or software that is essential to the functionality of the products. Service revenue not under contract is recognized upon the completion of the service performed. Revenue from spare parts sold on a stand-alone basis is recognized when control is transferred to the customer, which is generally at the time of shipment or delivery. Revenue from service contracts is recognized ratably over the contract period using a time-based method. These contracts represent an obligation to perform repair and other services including regulatory compliance qualification, calibration, certification, and preventative maintenance on a customer’s pre-defined equipment over the contract period. Leases The Company considers an arrangement a lease if the arrangement transfers the right to control the use of an identified asset in exchange for consideration. The Company has operating leases, but does not have financing leases. Operating lease right-of-use assets represent the right to use an underlying asset for the lease term, and lease liabilities represent the obligation to make payments arising from the lease agreement. These assets and liabilities are recognized at the commencement of the lease based upon the present value of the lease payments over the lease term. Lease payments include both lease and non-lease components for items or activities that transfer a good and service. Vehicle lease and non-lease components are separately accounted for based on standalone value. Real estate lease and non-lease components are accounted for as a single component. Operating lease right-of-use assets include initial direct costs, advanced lease payments and lease incentives. The lease term reflects the noncancellable period of the lease together with periods covered by an option to extend or terminate the lease when management is reasonably certain that it will exercise such option. The Company generally uses its incremental borrowing rate at the lease commencement date in determining the present value of lease payments as the information necessary to determine the rate implicit in the lease is not readily available. The incremental borrowing rate reflects similar terms by geographic location to the underlying leases. The Company's lease agreements do not contain any material residual value guarantees or material restrictive covenants. Lease expense for operating leases is recognized on a straight-line basis over the lease term. Variable lease payments consist of non-lease services related to the lease. Variable lease payments are excluded from the right-of-use asset and lease liabilities and are expensed as incurred. Short-term leases are less than one year without purchase or renewal options that are reasonably certain to be exercised and are recognized on a straight-line basis over the lease term. The right-of-use asset is tested for impairment in accordance with ASC 360. Warranty The Company generally offers one -year warranties on most of its products. Product warranties are recorded at the time revenue is recognized. While the Company engages in extensive product quality programs and processes, its warranty obligations are affected by product failure rates, material usage and service costs incurred in correcting a product failure. Employee Termination Benefits In situations where contractual termination benefits exist, the Company records accruals for employee termination benefits when it is probable that a liability has been incurred and the amount of the liability is reasonably estimable. All other employee termination arrangements are recognized and measured at their fair value at the communication date unless the employee is required to render additional service beyond the legal notification period, in which case the liability is recognized ratably over the future service period. Share-Based Compensation The Company recognizes share-based compensation expense within selling, general and administrative in the consolidated statements of operations and other comprehensive income with a corresponding offset to additional paid-in capital in the consolidated balance sheet. The Company recorded $4.5 million and $13.3 million of share-based compensation expense for the three and nine months ended September 30, 2019 , respectively, compared to $4.3 million and $12.5 million for the corresponding periods in 2018 . Research and Development Research and development costs primarily consist of salaries, consulting and other costs. The Company expenses these costs as incurred. Business Combinations and Asset Acquisitions The Company accounts for business acquisitions under the accounting standards for business combinations. The results of each acquisition are included in the Company's consolidated results as of the acquisition date. The purchase price of an acquisition is allocated to tangible and intangible assets and assumed liabilities based on their estimated fair values and any consideration in excess of the net assets acquired is recognized as goodwill. Acquisition transaction costs are expensed when incurred. In circumstances where an acquisition involves a contingent consideration arrangement, the Company recognizes a liability equal to the fair value of the expected contingent payments as of the acquisition date. Subsequent changes in the fair value of the contingent consideration are recorded to other charges (income), net. Recent Accounting Pronouncements In August 2018, the FASB issued ASU 2018-14 "Compensation - Retirement Benefit" which amends the current disclosure requirements for defined benefit pension plans and other post-retirement plans. The change in the disclosures will be applied retrospectively and become effective December 15, 2020 with early adoption permitted. The Company is currently evaluating the impact of this guidance on the benefit plan disclosures and the timing of adoption.

Revenue from Contract with Customer [Abstract]
Revenue from Contract with Customer [Text Block]	REVENUE On January 1, 2018, the Company adopted ASC 606 "Revenue from Contracts with Customers" and all the related amendments using the modified retrospective method, whereby the adoption does not impact any prior periods. The effect of adopting the new standard did not require any cumulative effect adjustment to retained earnings as of January 1, 2018. There was no impact to our consolidated statements of operations and comprehensive income, balance sheets, or statements of cash flows as of and for the period ended September 30, 2018. The Company disaggregates revenue from contracts with customers by product, service, timing of revenue recognition and geography. A summary by the Company’s reportable segments for the three and nine months ended September 30, 2019 and 2018 follows: For the three months ended September 30, 2019 U.S. Operations Swiss Operations Western European Operations Chinese Operations Other Operations Total Product Revenue $ 203,291 $ 26,114 $ 120,510 $ 129,163 $ 107,678 $ 586,756 Service Revenue: Point in time 53,035 5,191 31,852 10,111 27,665 127,854 Over time 12,712 2,110 16,290 3,018 5,126 39,256 Total $ 269,038 $ 33,415 $ 168,652 $ 142,292 $ 140,469 $ 753,866 For the three months ended September 30, 2018 U.S. Operations Swiss Operations Western European Operations Chinese Operations Other Operations Total Product Revenue $ 195,554 $ 24,791 $ 124,412 $ 127,050 $ 104,533 $ 576,340 Service Revenue: Point in time 48,910 4,663 29,365 10,200 25,645 118,783 Over time 10,915 2,009 19,393 2,848 4,558 39,723 Total $ 255,379 $ 31,463 $ 173,170 $ 140,098 $ 134,736 $ 734,846 For the nine months ended September 30, 2019 U.S. Operations Swiss Operations Western European Operations Chinese Operations Other Operations Total Product Revenue $ 580,155 $ 77,142 $ 352,260 $ 364,620 $ 302,853 $ 1,677,030 Service Revenue: Point in time 156,221 15,176 97,182 27,363 80,324 376,266 Over time 35,202 6,032 48,798 8,490 12,866 111,388 Total $ 771,578 $ 98,350 $ 498,240 $ 400,473 $ 396,043 $ 2,164,684 For the nine months ended September 30, 2018 U.S. Operations Swiss Operations Western European Operations Chinese Operations Other Operations Total Product Revenue $ 559,566 $ 75,520 $ 365,680 $ 351,052 $ 297,944 $ 1,649,762 Service Revenue: Point in time 146,515 14,410 92,331 28,212 74,853 356,321 Over time 30,517 6,152 54,303 8,037 12,571 111,580 Total $ 736,598 $ 96,082 $ 512,314 $ 387,301 $ 385,368 $ 2,117,663 A summary of revenue by major geographic destination for the three and nine months ended September 30 follows: Three Months Ended Nine Months Ended 2019 2018 2019 2018 Americas $ 298,304 $ 280,512 $ 849,282 $ 807,119 Europe 212,736 216,956 629,600 643,514 Asia / Rest of World 242,826 237,378 685,802 667,030 Total $ 753,866 $ 734,846 $ 2,164,684 $ 2,117,663 The Company's global revenue mix by product category is comprised of laboratory ( 52% of sales), industrial ( 41% of sales) and retail ( 7% of sales). The Company's product revenue by reportable segment is proportionately similar to the Company's global mix except the Company's Swiss Operations is largely comprised of laboratory products while the Company's Chinese Operations has a slightly higher percentage of industrial products. A summary of the Company’s revenue by product category for the three and nine months ended September 30 is as follows: Three Months Ended Nine Months Ended 2019 2018 2019 2018 Laboratory $ 388,441 $ 368,967 $ 1,127,833 $ 1,075,853 Industrial 315,337 305,248 889,716 873,181 Retail 50,088 60,631 147,135 168,629 Total $ 753,866 $ 734,846 $ 2,164,684 $ 2,117,663 The payment terms in the Company’s contracts with customers do not exceed one year and therefore contracts do not contain a significant financing component. In most cases, after appropriate credit evaluations, payments are due in arrears and are recognized as receivables. Unbilled revenue is recorded when performance obligations have been satisfied, but not yet billed to the customer. Unbilled revenue as of September 30, 2019 and December 31, 2018 was $21.6 million and $12.4 million respectively, and is included within accounts receivable. Deferred revenue and customer prepayments are recorded when cash payments are received or due in advance of the performance obligation being satisfied. Deferred revenue primarily includes prepaid service contracts, as well as deferred installation. Changes in the components of deferred revenue and customer prepayments during the periods ended September 30, 2019 and 2018: 2019 2018 Beginning balances as of January 1 $ 105,381 $ 107,166 Customer pre-payments/deferred revenue 466,617 469,173 Revenue recognized (442,904 ) (450,312 ) Foreign currency translation (2,169 ) (2,501 ) Ending balance as of September 30 $ 126,925 $ 123,526 The Company generally expenses sales commissions when incurred because the amortization period is one year or less. These costs are recorded within selling, general, and administrative expenses. The Company has not disclosed the value of unsatisfied performance obligations other than customer prepayments and deferred revenue above as most contracts have an expected length of one year or less and amounts greater than one year are immaterial.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities Disclosure [Text Block]	FINANCIAL INSTRUMENTS The Company has limited involvement with derivative financial instruments and does not use them for trading purposes. The Company enters into certain interest rate swap agreements in order to manage its exposure to changes in interest rates. The amount of the Company's fixed obligation interest payments may change based upon the expiration dates of its interest rate swap agreements and the level and composition of its debt. The Company also enters into certain foreign currency forward contracts to limit the Company's exposure to currency fluctuations on the respective hedged items. For additional disclosures on derivative instruments regarding balance sheet location, fair value, and the amounts reclassified into other comprehensive income and the effective portion of the cash flow hedges, also see Note 6 and Note 10 to the interim consolidated financial statements. As also mentioned in Note 8, the Company has designated its euro-denominated debt as a hedge of a portion of its net investment in euro-denominated foreign subsidiary. Cash Flow Hedges In June 2019, the Company entered into a cross currency swap arrangement designated as a cash flow hedge. The agreement converts $50 million of borrowings under the Company's credit facility into synthetic Swiss franc debt, which allows the Company to effectively change the floating rate LIBOR-based interest payments, excluding the credit spread to a fixed Swiss franc income of 0.82% . The swap began in June 2019 and matures in June 2023. In June 2019, the Company entered into a cross currency swap arrangement designated as a cash flow hedge. The agreement converts $50 million of borrowings under the Company's credit facility into synthetic Swiss franc debt, which allows the Company to effectively change the floating rate LIBOR-based interest payments, excluding the credit spread to a fixed Swiss franc income of 0.95% . The swap began in June 2019 and matures in June 2021. In February 2019, the Company entered into a cross currency swap arrangement designated as a cash flow hedge. The agreement converts $50 million of borrowings under the Company's credit facility into synthetic Swiss franc debt, which allows the Company to effectively change the floating rate LIBOR-based interest payments, excluding the credit spread to a fixed Swiss franc income of 0.78% . The swap began in February 2019 and matures in June 2021. In 2017, the Company entered into a cross currency swap arrangement designated as a cash flow hedge. The agreement converts $100 million of borrowings under the Company's credit facility into synthetic Swiss franc debt, which allows the Company to effectively change the floating rate LIBOR-based interest payments, including the credit spread to a fixed Swiss franc income of 0.01% . The swap began in June 2017 and matured in June 2019. In 2015, the Company entered into an interest rate swap agreement designated as a cash flow hedge. The agreement is a swap, which has the effect of changing the floating rate LIBOR-based interest payments associated with $100 million of borrowings under the Company's credit agreement to a fixed obligation of 2.25% beginning in February 2017 and matures in February 2022. In 2013, the Company entered into an interest rate swap agreement designated as a cash flow hedge. The agreement is a swap which has the effect of changing the floating rate LIBOR-based interest payments associated with $50 million of borrowings under the Company’s credit facility to a fixed obligation of 2.52% . The swap began in October 2015 and matures in October 2020. The Company's cash flow hedges are recorded gross at fair value in the consolidated balance sheet at September 30, 2019 and December 31, 2018 , respectively. A derivative gain of $2.7 million based upon interest rates and foreign currency rates at September 30, 2019 , is expected to be reclassified from other comprehensive income (loss) to earnings in the next twelve months. Through September 30, 2019 , no hedge ineffectiveness has occurred in relation to the cash flow hedges. Other Derivatives The Company enters into foreign currency forward contracts in order to economically hedge short-term trade and non-trade intercompany balances largely denominated in Swiss franc, other major European currencies, and the Chinese Renminbi with its foreign businesses. In accordance with U.S. GAAP, these contracts are considered “derivatives not designated as hedging instruments.” Gains or losses on these instruments are reported in current earnings. The foreign currency forward contracts are recorded at fair value in the consolidated balance sheet at September 30, 2019 and December 31, 2018 , respectively, and disclosed in Note 6. The Company recognized in other charges (income), a net loss of $3.7 million and $4.4 million during the three months ended September 30, 2019 and 2018 , respectively, and a net loss of $8.2 million and $0.2 million during the nine months ended September 30, 2019 and 2018 , respectively. The gains and losses are primarily offset by the underlying transaction gains and losses on the related intercompany balances. At September 30, 2019 and December 31, 2018 , these contracts had a notional value of $446.2 million and $436.7 million

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS At September 30, 2019 and December 31, 2018 , the Company had derivative assets totaling $0.6 million and $3.2 million respectively, and derivative liabilities totaling $5.6 million and $1.1 million , respectively. The Company has limited involvement with derivative financial instruments and therefore does not present all the required disclosures in tabular format. The fair values of the interest rate swap agreements, the cross-currency swap agreements and foreign currency forward contracts that economically hedge short-term intercompany balances are estimated based upon inputs from current valuation information obtained from dealer quotes and priced with observable market assumptions and appropriate valuation adjustments for credit risk. The Company has evaluated the valuation methodologies used to develop the fair values by dealers in order to determine whether such valuations are representative of an exit price in the Company’s principal market. In addition, the Company uses an internally developed model to perform testing on the valuations received from brokers. The Company has also considered both its own credit risk and counterparty credit risk in determining fair value and determined these adjustments were insignificant at September 30, 2019 and December 31, 2018 . Under U.S. GAAP, fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A fair value measurement consists of observable and unobservable inputs that reflect the assumptions that a market participant would use in pricing an asset or liability. A fair value hierarchy has been established that categorizes these inputs into three levels: Level 1: Quoted prices in active markets for identical assets and liabilities Level 2: Observable inputs other than quoted prices in active markets for identical assets and liabilities Level 3: Unobservable inputs The following table presents the Company's assets and liabilities, which are all categorized as Level 2 and are measured at fair value on a recurring basis at September 30, 2019 and December 31, 2018. The Company does not have any assets or liabilities that are categorized as Level 1 or Level 3. September 30, 2019 December 31, 2018 Balance Sheet Location Foreign currency forward contracts not designated as hedging instruments $ 558 $ 1,534 Other current assets and prepaid expenses Cash Flow Hedges: Interest rate swap agreements — 545 Other non-current assets Cross currency swap agreement — 1,154 Other current assets and prepaid expenses Total derivative assets $ 558 $ 3,233 Foreign currency forward contracts not designated as hedging instruments $ 2,254 $ 1,059 Accrued and other liabilities Cash Flow Hedges: Interest rate swap agreements 2,444 27 Other non-current liabilities Cross currency swap agreement 885 — Other non-current liabilities Total derivative liabilities $ 5,583 $ 1,086 At September 30, 2019 and December 31, 2018 , the Company had $12.8 million and $9.0 million of cash equivalents, respectively, the fair value of which is determined through quoted and corroborated prices in active markets. The fair value of cash equivalents approximates cost. The fair value of the Company's debt exceeds the carrying value by approximately $31.5 million as of September 30, 2019 . The fair value of the Company's fixed interest rate debt was estimated using Level 2 inputs, primarily discounted cash flow models, based on estimated current rates offered for similar debt under current market conditions for the Company.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES The Company's reported tax rate was 23.6% and 21% during the three months ended September 30, 2019 and 2018, respectively and 18.2% and 21.4% during the nine months ended September 30, 2019 and 2018, respectively. The provision for taxes is based upon using the Company's projected annual effective tax rate of 20% and 21.5% before non-recurring discrete tax items during 2019 and 2018, respectively. The difference between the Company's projected annual effective tax rate and the reported tax rate is primarily related to the timing of excess tax benefits associated with stock option exercises. In May 2019, a public referendum was held in Switzerland that approved Swiss federal tax reform proposals previously approved by Swiss Parliament. The changes in Swiss federal tax had an immaterial effect on the Company's financial statements. Additional changes in Swiss cantonal law were enacted in October 2019. The Company expects it will recognize a discrete non-cash deferred tax benefit as a result of the enactment of the cantonal law in the fourth quarter; however we are currently unable to reasonably estimate such amount as the Swiss authorities are still providing interpretive guidance on the new law and related transitional methodology. On December 22, 2017, the Tax Cuts and Jobs Act (the "Act") significantly revised U.S. corporate income tax law. The Company's accounting for the above items was based upon reasonable estimates of the tax effects of the Act, and its evaluation of recently issued regulatory guidance. In January 2019, further interpretive guidance was issued related to Transition Tax. The Company has completed its analysis of this recently issued guidance and concluded there is no additional impact to its financial position, results of operations, or cash flows.

The proceeds will be used to repay outstanding amounts on the Company's credit facility and fund operational expenses. The Company also entered into a forward contract to receive $149.9 million at the time of issuing the EUR 135 million Euro-Senior Notes. The Company issued the 1.30% Euro-Senior Notes with a fixed interest rate of 1.30% in November 2019. The 1.30% Euro-Senior Notes are unsecured obligations of the Company and will mature in November 1, 2034 . Interest on the 1.30% Euro-Senior Notes is payable semi-annually in April and November of each year. The Company will issue the 3.19% Senior Notes with a fixed interest rate of 3.19% in January 2020. The 3.19% Senior Notes are unsecured obligations of the Company and will mature in January 1, 2035 . Interest on the 3.19% Senior Notes is payable semi-annually in January and July of each year. The Company will designate the 1.30% Euro-Senior Notes as a hedge of a portion of its net investment in euro-denominated foreign subsidiaries to reduce foreign currency risk associated with the net investment in these operations. Changes in the fair value of this debt resulting from fluctuations in the euro to U.S. dollar exchange rates will be recorded as foreign currency translation adjustments within other comprehensive income (loss). The Company may at any time prepay the Senior Notes, in whole or in part, at a price equal to 100% of the principal amount thereof plus accrued and unpaid interest, and if applicable a "make-whole" prepayment premium and a swap related currency loss. 3.91% Senior Notes In April 2019, the Company entered into an agreement to issue and sell $75 million of ten-year Senior Notes in a private placement. The Company issued the Senior Notes with a fixed interest rate of 3.91% (" 3.91% Senior Notes") in June 2019. The 3.91% Senior Notes are unsecured obligations of the Company and will mature in June 2029 . Interest on the 3.91% Senior Notes is payable semi-annually in June and December of each year. The proceeds were used to repay outstanding amounts on the Company's credit facility. The 3.91% Senior Notes, the 1.30% Euro-Senior Notes and the 3.19% Senior Notes contain customary affirmative and negative covenants for agreements of this type that are substantially similar to those contained in previously issued debt of the Company. The 3.91% Senior Notes, 1.30% Euro-Senior Notes and the 3.19% Senior Notes also contain customary events of default with customer grace periods, as applicable. 1.47% Euro Senior Notes The Company has designated the 1.47% Euro Senior Notes as a hedge of a portion of its net investment in euro-denominated foreign subsidiaries to reduce foreign currency risk associated with the net investment in these operations. Changes in the carrying value of this debt resulting from fluctuations in the euro to U.S. dollar exchange rate are recorded as foreign currency translation adjustments within other comprehensive income (loss). The pre-tax unrealized gain (loss) recorded in other comprehensive income (loss) related to this net investment hedge was a gain of $5.3 million and a loss of $1.8 million for the three months ended September 30, 2019 and 2018, respectively, and a gain of $6.3 million and $2.8 million for the nine month periods ended September 30, 2019 and 2018, respectively. The Company has a gain of $5.0 million recorded in accumulated other comprehensive income (loss) as of September 30, 2019. Other Local Arrangements In April 2018, two of the Company's non-U.S. pension plans issued loans totaling $39.6 million (Swiss franc 38 million ) to a wholly owned subsidiary of the Company. The loans have the same terms and conditions, which include an interest rate of Swiss franc LIBOR plus 87.5 basis points. The loans were renewed for one year in April 2019 and, as such, are classified as short-term debt on the Company's consolidated balance sheet.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2019
Accounting Policies [Abstract]
Trade Accounts Receivable	Trade Accounts Receivable Trade accounts receivable are recorded at the invoiced amount and do not bear interest. The allowance for doubtful accounts represents the Company’s best estimate of probable credit losses in its existing trade accounts receivable. The Company determines the allowance based upon a review of both specific accounts for collection and the age of the accounts receivable portfolio.
Inventories	Inventories Inventories are valued at the lower of cost or net realizable value. Cost, which includes direct materials, labor and overhead, is generally determined using the first in, first out (FIFO) method. The estimated net realizable value is based on assumptions for future demand and related pricing. Adjustments to the cost basis of the Company’s inventory are made for excess and obsolete items based on usage, orders and technological obsolescence. If actual market conditions are less favorable than those projected by management, reductions in the value of inventory may be required. Inventories consisted of the following: September 30, December 31, Raw materials and parts $ 128,371 $ 122,945 Work-in-progress 45,843 47,098 Finished goods 106,764 98,778 $ 280,978 $ 268,821
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Goodwill, representing the excess of purchase price over the net asset value of companies acquired, and indefinite-lived intangible assets are not amortized, but are reviewed for impairment annually in the fourth quarter, or more frequently if events or changes in circumstances indicate that an asset might be impaired. The annual evaluation for goodwill and indefinite-lived intangible assets are generally based on an assessment of qualitative and quantitative factors to determine whether it is more likely than not that the fair value of the asset is less than its carrying amount. Other intangible assets include indefinite-lived assets and assets subject to amortization. Where applicable, amortization is charged on a straight-line basis over the expected period of benefit. The straight-line method of amortization reflects an appropriate allocation of the cost of the intangible assets to earnings in proportion to the amount of economic benefits obtained by the Company in each reporting period. The Company assesses the initial acquisition of intangible assets in accordance with the provisions of ASC 805 "Business Combinations" and the continued accounting for previously recognized intangible assets and goodwill in accordance with the provisions of ASC 350 "Intangible - Goodwill and Other" and ASC 360 "Property, Plant and Equipment". Other intangible assets consisted of the following: September 30, 2019 December 31, 2018 Gross Amount Accumulated Amortization Intangibles, Net Gross Amount Accumulated Amortization Intangibles, Net Customer relationships $ 197,467 $ (56,508 ) $ 140,959 $ 197,942 $ (49,887 ) $ 148,055 Proven technology and patents 75,482 (46,076 ) 29,406 73,880 (42,750 ) 31,130 Tradenames (finite life) 4,482 (2,981 ) 1,501 4,504 (2,874 ) 1,630 Tradenames (indefinite life) 35,442 — 35,442 35,500 — 35,500 Other 5,455 (3,392 ) 2,063 3,684 (2,691 ) 993 $ 318,328 $ (108,957 ) $ 209,371 $ 315,510 $ (98,202 ) $ 217,308 The Company recognized amortization expense associated with the above intangible assets of $3.8 million and $3.6 million for the three months ended September 30, 2019 and 2018 , respectively and $11.3 million and $10.7 million for the nine months ended September 30, 2019 and 2018 , respectively. The annual aggregate amortization expense based on the current balance of other intangible assets is estimated at $15.1 million for 2019 , $15.4 million for 2020 , $14.1 million for 2021 , $12.7 million for 2022 , $13.3 million for 2023 and $11.7 million for 2024 . Purchased intangible amortization was $3.7 million , $2.8 million after tax, and $3.4 million , $2.5 million after tax, for the three months ended September 30, 2019 and 2018 , respectively and $10.6 million , $8.0 million after tax, and $10.0 million , $7.5 million after tax, for the nine months ended September 30, 2019 and 2018 , respectively.

Revenue Recognition	Revenue Recognition Product revenue is recognized from contracts with customers when a customer has obtained control of a product. The Company considers control to have transferred based upon shipping terms. To the extent the Company’s arrangements have a separate performance obligation, revenue related to any post-shipment performance obligation is deferred until completed. Shipping and handling costs charged to customers are included in total net sales and the associated expense is a component of cost of sales. Certain products are also sold through indirect distribution channels whereby the distributor assumes any further obligations to the end customer. Revenue is recognized on these distributor arrangements upon transfer of control to the distributor. Contracts do not contain variable pricing arrangements that are retrospective, except for rebate programs. Rebates are estimated based on expected sales volumes and offset against revenue at the time such revenue is recognized. The Company generally maintains the right to accept or reject a product return in its terms and conditions and also maintains appropriate accruals for outstanding credits. The related provisions for estimated returns and rebates are immaterial to the consolidated financial statements. Certain of the Company’s product arrangements include separate performance obligations, primarily related to installation. Such performance obligations are accounted for separately when the deliverables have stand-alone value and the satisfaction of the undelivered performance obligations is probable and within the Company's control. The allocation of revenue between the performance obligations is based on the observable stand-alone selling prices at the time of the sale in accordance with a number of factors including service technician billing rates, time to install, and geographic location. Software is generally not considered a distinct performance obligation with the exception of a few small software applications. The Company generally does not sell software products without the related hardware instrument as the software is embedded in the product. The Company’s products typically require no significant production, modification, or customization of the hardware or software that is essential to the functionality of the products. Service revenue not under contract is recognized upon the completion of the service performed. Revenue from spare parts sold on a stand-alone basis is recognized when control is transferred to the customer, which is generally at the time of shipment or delivery. Revenue from service contracts is recognized ratably over the contract period using a time-based method. These contracts represent an obligation to perform repair and other services including regulatory compliance qualification, calibration, certification, and preventative maintenance on a customer’s pre-defined equipment over the contract period.
Lessee, Leases [Policy Text Block]	Leases The Company considers an arrangement a lease if the arrangement transfers the right to control the use of an identified asset in exchange for consideration. The Company has operating leases, but does not have financing leases. Operating lease right-of-use assets represent the right to use an underlying asset for the lease term, and lease liabilities represent the obligation to make payments arising from the lease agreement. These assets and liabilities are recognized at the commencement of the lease based upon the present value of the lease payments over the lease term. Lease payments include both lease and non-lease components for items or activities that transfer a good and service. Vehicle lease and non-lease components are separately accounted for based on standalone value. Real estate lease and non-lease components are accounted for as a single component. Operating lease right-of-use assets include initial direct costs, advanced lease payments and lease incentives. The lease term reflects the noncancellable period of the lease together with periods covered by an option to extend or terminate the lease when management is reasonably certain that it will exercise such option. The Company generally uses its incremental borrowing rate at the lease commencement date in determining the present value of lease payments as the information necessary to determine the rate implicit in the lease is not readily available. The incremental borrowing rate reflects similar terms by geographic location to the underlying leases. The Company's lease agreements do not contain any material residual value guarantees or material restrictive covenants. Lease expense for operating leases is recognized on a straight-line basis over the lease term. Variable lease payments consist of non-lease services related to the lease. Variable lease payments are excluded from the right-of-use asset and lease liabilities and are expensed as incurred. Short-term leases are less than one year without purchase or renewal options that are reasonably certain to be exercised and are recognized on a straight-line basis over the lease term. The right-of-use asset is tested for impairment in accordance with ASC 360.
Warranty	Warranty The Company generally offers one -year warranties on most of its products. Product warranties are recorded at the time revenue is recognized. While the Company engages in extensive product quality programs and processes, its warranty obligations are affected by product failure rates, material usage and service costs incurred in correcting a product failure.
Employee Termination Benefits	Employee Termination Benefits In situations where contractual termination benefits exist, the Company records accruals for employee termination benefits when it is probable that a liability has been incurred and the amount of the liability is reasonably estimable. All other employee termination arrangements are recognized and measured at their fair value at the communication date unless the employee is required to render additional service beyond the legal notification period, in which case the liability is recognized ratably over the future service period.
Share - Based Compensation	Share-Based Compensation The Company recognizes share-based compensation expense within selling, general and administrative in the consolidated statements of operations and other comprehensive income with a corresponding offset to additional paid-in capital in the consolidated balance sheet. The Company recorded $4.5 million and $13.3 million of share-based compensation expense for the three and nine months ended September 30, 2019 , respectively, compared to $4.3 million and $12.5 million for the corresponding periods in 2018 .
Research and Development	Research and Development Research and development costs primarily consist of salaries, consulting and other costs. The Company expenses these costs as incurred.
Business Combinations Policy [Policy Text Block]	Business Combinations and Asset Acquisitions The Company accounts for business acquisitions under the accounting standards for business combinations. The results of each acquisition are included in the Company's consolidated results as of the acquisition date. The purchase price of an acquisition is allocated to tangible and intangible assets and assumed liabilities based on their estimated fair values and any consideration in excess of the net assets acquired is recognized as goodwill. Acquisition transaction costs are expensed when incurred. In circumstances where an acquisition involves a contingent consideration arrangement, the Company recognizes a liability equal to the fair value of the expected contingent payments as of the acquisition date. Subsequent changes in the fair value of the contingent consideration are recorded to other charges (income), net.
New Accounting Pronouncements, Policy [Policy Text Block]	Recent Accounting Pronouncements In August 2018, the FASB issued ASU 2018-14 "Compensation - Retirement Benefit" which amends the current disclosure requirements for defined benefit pension plans and other post-retirement plans. The change in the disclosures will be applied retrospectively and become effective December 15, 2020 with early adoption permitted. The Company is currently evaluating the impact of this guidance on the benefit plan disclosures and the timing of adoption.
