Revenue from Contract with Customer [Abstract]
Revenue	3. Revenues The Company adopted ASC 606 as of January 1, 2018 using the modified retrospective method. The cumulative adjustment made to the January 1, 2018 consolidated balance sheet for the adoption of ASC 606 was to increase Retained earnings by $4.2 million, increase Total assets by $7.9 million and increase Total liabilities by $3.7 million. The outstanding contract asset and liability accounts were as follows: 2019 2018 (In thousands) Contract assets - January 1 $ 58,266 $ 32,658 Contract assets – September 30 78,010 60,037 Change in contract assets – increase 19,744 27,379 Contract liabilities – January 1 146,162 117,058 Contract liabilities – September 30 152,897 145,247 Change in contract liabilities – increase (6,735 ) (28,189 ) Net change $ 13,009 $ (810 ) The net change for the nine months ended September 30, 2019 was primarily driven by the recognition of revenue as performance obligations were satisfied prior to billing and exceeded receipt of advance payments from customers. For the nine months ended September 30, 2019 and 2018, the Company recognized revenue of $123.6 million and $95.0 million, respectively, that was previously included in the beginning balance of contract liabilities. Contract assets are reported as a component of Other current assets in the consolidated balance sheet. At September 30, 2019 and December 31, 2018, $8.7 million and $8.9 million of Customer advanced payments (contract liabilities), respectively, were recorded in Other long-term liabilities in the consolidated balance sheets. Applying the practical expedient available under ASC 606, the remaining performance obligations exceeding one year as of September 30, 2019 and December 31, 2018 were $196.6 million and $187.2 million, respectively. Remaining performance obligations represent the transaction price of firm, noncancelable orders, with expected delivery dates to customers greater than one year from the balance sheet date, for which the performance obligation is unsatisfied or partially unsatisfied. These performance obligations will be substantially satisfied within two to three years. Geographic Areas Information about the Company’s operations in different geographic areas is shown below.

Fair Value Disclosures [Abstract]
Fair Value Measurements	5. Fair Value Measurements Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The Company utilizes a valuation hierarchy for disclosure of the inputs to the valuations used to measure fair value. This hierarchy prioritizes the inputs into three broad levels as follows. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3 inputs are unobservable inputs based on the Company’s own assumptions used to measure assets and liabilities at fair value. A financial asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. The following table provides the Company’s assets that are measured at fair value on a recurring basis, consistent with the fair value hierarchy, at September 30, 2019 and December 31, 2018: September 30, 2019 December 31, 2018 Fair Value Fair Value (In thousands) Fixed-income investments $ 8,108 $ 7,655 The fair value of fixed-income investments, which are valued as level 1 investments, was based on quoted market prices. The fixed-income investments are shown as a component of investments and other assets on the consolidated balance sheet. For the nine months ended September 30, 2019 and 2018, gains and losses on the investments noted above were not significant. No transfers between level 1 and level 2 investments occurred during the nine months ended September 30, 2019 and 2018. Financial Instruments Cash, cash equivalents and fixed-income investments are recorded at fair value at September 30, 2019 and December 31, 2018 in the accompanying consolidated balance sheet. The following table provides the estimated fair values of the Company’s financial instrument liabilities, for which fair value is measured for disclosure purposes only, compared to the recorded amounts at September 30, 2019 and December 31, 2018: September 30, 2019 December 31, 2018 Recorded Fair Value Recorded Fair Value (In thousands) Long-term debt, net (including current portion) $ (2,432,451 ) $ (2,612,882 ) $ (2,378,809 ) $ (2,368,676 ) The fair value of net short-term Foreign Currency At September 30, 2019, the Company had no forward contracts outstanding. For the nine months ended September 30, 2019 and 2018, realized gains and losses on foreign currency forward contracts were not significant.

Leases [Abstract]
Leases	8. Leases The Company determines if an arrangement is a lease at inception. This determination generally depends on whether the arrangement conveys to the Company the right to control the use of an explicitly or implicitly identified fixed asset for a period of time in exchange for consideration. Control of an underlying asset is conveyed to the Company if the Company obtains the rights to direct the use of and to obtain substantially all of the economic benefits from using the underlying asset. The Company has lease agreements which include lease and non-lease Operating leases are included in ROU assets, accrued liabilities and other, and other long-term liabilities on our consolidated balance sheets. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. Operating lease payments are recognized as lease expense on a straight-line basis over the lease term. The Company has no material finance leases. The Company primarily leases buildings (real estate) and automobiles which are classified as operating leases. ASC 842 requires a lessee to discount its unpaid lease payments using the interest rate implicit in the lease or, if that rate cannot be readily determined, its incremental borrowing rate. As an implicit interest rate is not readily determinable in our leases, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The lease term for all of the Company’s leases includes the non-cancellable been excluded from the lease term (and lease liability) for the majority of the Company’s leases as the reasonably certain threshold is not met. In a small number of the Company’s leases, the options for renewals have been included in the lease term as the reasonably certain threshold is met due to the Company having significant economic incentive for extending the lease. Lease payments included in the measurement of the lease liability are comprised of fixed payments, variable payments that depend on an index or rate and amounts probable to be payable under the exercise of the Company option to purchase the underlying asset if reasonably certain. Variable lease payments not dependent on a rate or index associated with the Company’s leases are recognized when the events, activities, or circumstances in the lease agreement on which those payments are assessed are probable. Variable lease payments are presented as operating expense in the Company’s income statement in the same line item as expense arising from fixed lease payments. The Company has commitments under operating leases for certain facilities, vehicles and equipment used in its operations. Our leases have initial lease terms ranging from one month to 14 years. Certain lease agreements contain provisions for future rent increases.

Business Combinations [Abstract]
Acquisitions	9. Acquisitions The Company spent $122.1 million in cash, net of cash acquired, to acquire Pacific Design Technologies, Inc. (“PDT”) in September 2019. PDT designs and manufactures a complete range of custom-engineered, liquid cooling systems and components used in a broad set of current and next-generation commercial aerospace, defense and space platforms. PDT was privately held and is headquartered in Goleta, California. PDT is part of EMG. The following table represents the preliminary allocation of the purchase price for the net assets of the PDT acquisition based on the estimated fair values at acquisition (in millions): Property, plant and equipment $ 1.0 Goodwill 47.0 Other intangible assets 63.7 Net working capital and other (1) 10.4 Total cash paid $ 122.1 (1) Includes $7.4 million in accounts receivable, whose fair value, contractual cash flows and expected cash flows are approximately equal. The amount allocated to goodwill is reflective of the benefits the Company expects to realize from the 2019 acquisition as follows: PDT’s products and solutions enhance the Company’s position and broaden the Company’s differentiated product offerings in the aerospace and defense sectors. At September 30, 2019, the purchase price allocated to other intangible assets of $63.7 million consists of $10.0 million of indefinite-lived intangible trade names, which are not subject to amortization. The remaining $53.7 million of other intangible assets consists of $43.7 million of customer relationships, which are being amortized over a period of 18 years, and $10.0 million of purchased technology, which is being amortized over a period of 18 years. Amortization expense for each of the next five years for the 2019 acquisition is expected to approximate $3 million per year. The Company is in the process of finalizing the measurement of certain tangible and intangible assets and liabilities for its 2019 acquisition including inventory, property, plant and equipment, goodwill, trade names, customer relationships and purchased technology and the accounting for income taxes. The Company finalized the measurement of its goodwill and other intangible assets related to its fourth quarter of 2018 acquisitions, which had no material impact to the consolidated statement of income. The Company is in the process of finalizing the accounting for income taxes for its fourth quarter of 2018 acquisitions of Telular and Spectro Scientific. The 2019 acquisition had an immaterial impact on reported net sales, net income and diluted earnings per share for the three and nine months ended September 30, 2019. Had the acquisition been made at the beginning of 2019 or 2018, unaudited pro forma net sales, net income and diluted earnings per share for the three and nine months ended September 30, 2019 and 2018, respectively, would not have been materially different than the amounts reported. Acquisition subsequent to September 30, 2019 In October 2019, the Company acquired Gatan from Roper Technologies, Inc. for approximately $925 million in cash. Gatan has annual sales of approximately $180 million. Gatan is a leading manufacturer of instrumentation and software used to enhance and extend the operation and performance of electron microscopes. Gatan will join EIG.

The Company used historical exercise data to estimate the stock options’ expected term, which represents the period of time that the stock options granted are expected to be outstanding. Management anticipates that the future stock option holding periods will be similar to the historical stock option holding periods. The risk-free interest rate for periods within the expected term of the stock option is based on the U.S. Treasury yield curve at the time of grant. The expected dividend yield is calculated by dividing the Company’s annual dividend, based on the most recent quarterly dividend rate, by the Company’s closing common stock price on the grant date. Compensation expense recognized for all share-based awards is net of estimated forfeitures. The Company’s estimated forfeiture rates are based on its historical experience.

As of September 30, 2019, there was approximately $22.3 million of expected future pre-tax two years The fair value of restricted shares under the Company’s restricted stock arrangement is determined by the product of the number of shares granted and the Company’s closing common stock price on the grant date. Upon the grant of restricted stock, the fair value of the restricted shares (unearned compensation) at the grant date is charged as a reduction of capital in excess of par value in the Company’s consolidated balance sheet and is amortized to expense on a straight-line basis over the vesting period, which is the same as the calculated derived service period as determined on the grant date.

Contingencies	15. Contingencies Asbestos Litigation The Company (including its subsidiaries) has been named as a defendant in a number of asbestos-related lawsuits. Certain of these lawsuits relate to a business which was acquired by the Company and do not involve products which were manufactured or sold by the Company. In connection with these lawsuits, the seller of such business has agreed to indemnify the Company against these claims (the “Indemnified Claims”). The Indemnified Claims have been tendered to, and are being defended by, such seller. The seller has met its obligations, in all respects, and the Company does not have any reason to believe such party would fail to fulfill its obligations in the future. To date, no judgments have been rendered against the Company as a result of any asbestos-related lawsuit. The Company believes that it has good and valid defenses to each of these claims and intends to defend them vigorously. Environmental Matters Certain historic processes in the manufacture of products have resulted in environmentally hazardous waste by-products non-AMETEK-owned “non-owned” agreed-to non-de non-owned Total environmental reserves at September 30, 2019 and December 31, 2018 were $28.5 million and $27.8 million, respectively, for both non-owned The Company has agreements with other former owners of certain of its acquired businesses, as well as new owners of previously owned businesses. Under certain of the agreements, the former or new owners retained, or assumed and agreed to indemnify the Company against, certain environmental and other liabilities under certain circumstances. The Company and some of these other parties also carry insurance coverage for some environmental matters. To date, these parties have met their obligations in all material respects. The Company believes it has established reserves for the environmental matters described above, which are sufficient to perform all known responsibilities under existing claims and consent orders. The Company has no reason to believe that other third parties would fail to perform their obligations in the future. In the opinion of management, based on presently available information and the Company’s historical experience related to such matters, an adequate provision for probable costs has been made and the ultimate cost resulting from these actions is not expected to materially affect the consolidated results of operations, financial position or cash flows of the Company. The Company has been remediating groundwater contamination for several contaminants, including trichloroethylene (“TCE”), at a formerly owned site in El Cajon, California. Several lawsuits have been filed against the Company alleging damages resulting from the groundwater contamination, including property damages and personal injury, and seeking compensatory and punitive damages.
