Accounting Changes and Error Corrections [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements Recently Adopted Accounting Pronouncements Effective January 1, 2020, the Company adopted ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), using the modified retrospective transition method. ASU 2016-13 provides guidance on the estimation of current expected credit losses on financial instruments, including trade receivables. ASU 2016-13 requires entities to consider a broad range of information to estimate expected credit losses, including increased forward-looking information, which may result in earlier recognition of losses when compared to prior standards. The adoption of ASU 2016-13 In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (“ASU 2018-13”), which changes the fair value measurement disclosure requirements of ASC Topic 820, Fair Value Measurement (“ASC 820”), by eliminating, modifying and adding to those requirements. ASU 2018-13 also modifies the disclosure objective paragraphs of ASC 820 to eliminate (1) “at a minimum” from the phrase “an entity shall disclose at a minimum” and (2) other similar “open ended” disclosure requirements to promote the appropriate exercise of discretion by entities. The Company prospectively adopted ASU 2018-13, effective January 1, 2020, and the adoption did not have a significant impact on the Company’s consolidated results of operations, financial position, cash flows and financial statement disclosures. In August 2018, the FASB issued ASU No. 2018-15, Intangibles–Goodwill and Other–Internal-Use Software (“ASU 2018-15”), that requires implementation costs incurred by customers in cloud computing arrangements to be deferred and recognized over the term of the arrangement, if those costs would be capitalized by the customer in a software licensing arrangement under the internal-use software guidance in ASC Topic 350, Intangibles–Goodwill and Other. ASU 2018-15 requires a customer to disclose the nature of its hosting arrangements that are service contracts and provide disclosures as if the deferred implementation costs were a separate, major depreciable asset class. The Company prospectively adopted ASU 2018-15, effective January 1, 2020, and the adoption did not have a significant impact on the Company’s consolidated results of operations, financial position, cash flows and financial statement disclosures. Recent Accounting Pronouncements In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”), which simplifies the accounting for income taxes by removing certain exceptions to the general principles in ASC Topic 740. ASU 2019-12 is effective for fiscal years beginning after December 15, 2021. Early adoption is permitted and the amendments in this ASU should be applied on a retrospective basis to all periods presented. The Company has not determined the impact ASU 2019-12 may have on the Company’s consolidated results of operations, financial position, cash flows or financial statement disclosures. In August 2018, the FASB issued ASU No. 2018-14, Compensation–Retirement Benefits–Defined Benefit Plans–General (“ASU 2018-14”), which changes the disclosure requirements of ASC Topic 715, Compensation – Retirement Benefits, by eliminating, modifying and adding to those requirements. ASU 2018-14 is effective for fiscal years beginning after December 15, 2020. Early adoption is permitted and the amendments in this ASU should be applied on a retrospective basis to all periods presented. The Company has not determined the impact ASU 2018-14 may have on the Company’s consolidated financial statement disclosures.

The warranty periods for products sold vary among the Company’s operations, but the majority do not exceed one year. The Company calculates its warranty expense provision based on its historical warranty experience and adjustments are made periodically to reflect actual warranty expenses. Product warranty obligations are reported as a component of Accrued liabilities and other in the consolidated balance sheet. Changes in the accrued product warranty obligation were as follows: Nine Months Ended September 30, 2020 2019 (In thousands) Balance at the beginning of the period $ 27,611 $ 23,482 Accruals for warranties issued during the period 9,766 14,342 Settlements made during the period (11,513) (13,335) Warranty accruals related to acquired businesses and other during the period 2,594 617 Balance at the end of the period $ 28,458 $ 25,106 Accounts Receivable The Company maintains allowances for estimated losses resulting from the inability of customers to meet their financial obligations to the Company. The Company recognizes an allowance for doubtful accounts, on all accounts receivable, which considers the length of time receivables are past due, customers’ billing exposure, ability to pay, and contract terms. The Company also considers general and market business conditions, country, and political risk. Balances are written off when determined to be uncollectible. At September 30, 2020, the Company recorded $614.8 million of accounts and notes receivable, net of allowances of $12.6 million. Changes in the allowance were not material for the three and nine months ended September 30, 2020.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share The calculation of basic earnings per share is based on the weighted average number of common shares considered outstanding during the periods. The calculation of diluted earnings per share reflects the effect of all potentially dilutive securities (principally outstanding stock options and restricted stock grants). Securities that are anti-dilutive have been excluded and are not significant. The number of weighted average shares used in the calculation of basic earnings per share and diluted earnings per share was as follows: Three Months Ended September 30, Nine Months Ended September 30, 2020 2019 2020 2019 (In thousands) Weighted average shares: Basic shares 229,576 228,041 229,254 227,493 Equity-based compensation plans 1,884 1,519 1,650 1,698 Diluted shares 231,460 229,560 230,904 229,191

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	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, 2020 and December 31, 2019: September 30, 2020 December 31, 2019 Fair Value Fair Value (In thousands) Mutual fund investments $ 8,177 $ 8,390 The fair value of mutual fund investments, which are valued as level 1 investments, was based on quoted market prices. The mutual fund investments are shown as a component of investments and other assets on the consolidated balance sheet. For the nine months ended September 30, 2020 and 2019, 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, 2020 and 2019. Financial Instruments Cash, cash equivalents and mutual fund investments are recorded at fair value at September 30, 2020 and December 31, 2019 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, 2020 and December 31, 2019: September 30, 2020 December 31, 2019 Recorded Amount Fair Value Recorded Amount Fair Value (In thousands) Long-term debt, net (including current portion) $ (2,299,924) $ (2,492,828) $ (2,382,041) $ (2,531,549) The fair value of net short-term borrowings approximates the carrying value. Net short-term borrowings are valued as level 2 liabilities as they are corroborated by observable market data. The Company’s net long-term debt is all privately held with no public market for this debt, therefore, the fair value of net long-term debt was computed based on comparable current market data for similar debt instruments and is considered a level 3 liability. Foreign Currency At September 30, 2020, the Company had a Canadian dollar forward contract for a total notional value of 24.0 million Canadian dollars and an immaterial unrealized gain outstanding. For the nine months ended September 30, 2020 and 2019, realized gains and losses on foreign currency forward contracts were not significant. The Company does not typically designate its foreign currency forward contracts as hedges.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Hedging Activities	Hedging Activities The Company has designated certain foreign-currency-denominated long-term borrowings as hedges of the net investment in certain foreign operations. As of September 30, 2020, these net investment hedges included British-pound-and Euro-denominated long-term debt. These borrowings were designed to create net investment hedges in certain designated foreign subsidiaries. The Company designated the British-pound- and Euro-denominated loans referred to above as hedging instruments to offset translation gains or losses on the net investment due to changes in the British pound and Euro exchange rates. These net investment hedges are evidenced by management’s contemporaneous documentation supporting the hedge designation. Any gain or loss on the hedging instruments (the debt) following hedge designation is reported in accumulated other comprehensive income in the same manner as the translation adjustment on the hedged investment based on changes in the spot rate, which is used to measure hedge effectiveness. At September 30, 2020, the Company had $290.7 million of British-pound-denominated loans, which were designated as a hedge against the net investment in British pound functional currency foreign subsidiaries. At September 30, 2020, the Company had $670.8 million in Euro-denominated loans, which were designated as a hedge against the net investment in Euro functional currency foreign subsidiaries. As a result of the British-pound- and Euro-denominated loans designated and 100% effective as net investment hedges, $15.1 million of pre-tax currency remeasurement losses have been included in the foreign currency translation component of other comprehensive income for the nine months ended September 30, 2020.

Leases

Leases [Abstract]
Leases	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 components, which the Company has elected to account for as a single lease component for all classes of underlying assets. Lease expense for variable lease components are recognized when the obligation is probable. Operating leases are included in right of use assets, accrued liabilities and other, and other long-term liabilities on our consolidated balance sheets. Operating lease right of use 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 period of the lease plus any additional periods covered by either a Company option to extend (or not to terminate) the lease that the Company is reasonably certain to exercise, or an option to extend (or not to terminate) the lease controlled by the lessor. Options for lease renewals have 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. Cash used in operations for operating leases was not materially different from operating lease expense for the nine months ended September 30, 2020 and September 30, 2019. The Company's leases have initial lease terms ranging from one month to 14 years. Certain lease agreements contain provisions for future rent increases. The components of lease expense were as follows: Three Months Ended Nine Months Ended 2020 2019 2020 2019 (In thousands) Operating lease cost $ 10,715 $ 10,500 $ 31,704 $ 29,209 Variable lease cost 1,611 543 3,701 3,073 Total lease cost $ 12,326 $ 11,043 $ 35,405 $ 32,282 Supplemental balance sheet information related to leases was as follows: September 30, December 31, (In thousands) Right of use assets, net $ 166,728 $ 179,679 Lease liabilities included in Accrued Liabilities and other 43,219 43,025 Lease liabilities included in Other long-term liabilities 129,286 142,620 Total lease liabilities $ 172,505 $ 185,645 Supplemental cash flow information and other information related to leases was as follows: Nine Months Ended 2020 2019 (In thousands) Right-of-use assets obtained in exchange for new operating liabilities $ 25,981 $ 12,952 Weighted-average remaining lease terms—operating leases (years) 5.56 5.93 Weighted-average discount rate—operating leases 3.56 % 3.81 % Maturities of lease liabilities as of September 30, 2020 were as follows: Lease Liability Maturity Analysis Operating Leases (In thousands) Remaining 2020 $ 12,793 2021 46,702 2022 38,489 2023 29,394 2024 19,764 Thereafter 42,595 Total lease payments 189,737 Less: imputed interest 17,232 $ 172,505 The Company does not have any significant leases that have not yet commenced.

Business Combinations [Abstract]
Acquisition and Divestiture	Acquisition and Divestiture Acquisition The Company spent $116.5 million in cash, net of cash acquired, to acquire IntelliPower in January 2020. IntelliPower designs and manufactures a broad portfolio of ruggedized solutions including uninterruptible power systems, external battery packs, power distribution units and power conditioners. IntelliPower was privately held and is headquartered in Orange, California. IntelliPower is part of EIG. The following table represents the allocation of the purchase price for the net assets of the IntelliPower acquisition based on the estimated fair values at acquisition (in millions): Property, plant and equipment $ 1.8 Goodwill 58.0 Other intangible assets 59.5 Deferred income taxes (13.1) Net working capital and other (1) 10.3 Total cash paid $ 116.5 ________________ (1) Includes $6.4 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 as IntelliPower’s products and solutions broaden the Company’s differentiated product offerings in the power systems and instruments sectors. At September 30, 2020, the purchase price allocated to other intangible assets of $59.5 million consists of $9.0 million of indefinite-lived intangible trade names, which are not subject to amortization. The remaining $50.5 million of other intangible assets consists of $38.0 million of customer relationships, which are being amortized over a period of 20 years, and $12.5 million of purchased technology, which is being amortized over a period of 15 years. Amortization expense for each of the next five years for the 2020 acquisition is expected to approximate $3 million per year. The Company finalized the measurement of certain tangible assets and liabilities for its 2020 acquisition of IntelliPower, as well as the accounting for income taxes. The Company finalized the measurement of its goodwill and other intangible assets related to its fourth quarter of 2019 acquisition of Gatan, which had no material impact to the Company's Statement of Income. The IntelliPower 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, 2020. Had the acquisition been made at the beginning of 2020 or 2019, unaudited pro forma net sales, net income and diluted earnings per share for the three and nine months ended September 30, 2020 and 2019, respectively, would not have been materially different than the amounts reported. Divestiture The Company completed its sale of Reading Alloys to Kymera International in March 2020 for net cash proceeds of $245.3 million. The sale resulted in a pretax gain of $141.0 million, recorded in Other income (expense), net in the Consolidated Statement of Income, and income tax expense of approximately $31.4 million in connection with the sale. Reading Alloys revenue and costs were reported within the EMG segment through the date of sale.

Income Taxes	Income Taxes At September 30, 2020, the Company had gross uncertain tax benefits of $95.1 million, of which $56.8 million, if recognized, would impact the effective tax rate. The following is a reconciliation of the liability for uncertain tax positions (in millions): Balance at December 31, 2019 $ 109.1 Additions for tax positions 15.3 Reductions for tax positions (29.3) Balance at September 30, 2020 $ 95.1 The Company recognizes interest and penalties accrued related to uncertain tax positions in income tax expense. The amounts recognized in income tax expense for interest and penalties during the three and nine months ended September 30, 2020 and 2019 were not significant. The effective tax rate for the three months ended September 30, 2020 was 17.5%, compared with 19.5% for the three months ended September 30, 2019. The effective tax rate for the nine months ended September 30, 2020 was 19.1%, compared with 20.1% for the nine months ended September 30, 2019. The lower rate for 2020 reflects the results of tax planning initiatives and lower overall foreign tax expense partially offset by lower year over year tax benefits related to share-based payment transactions.

Share-based Payment Arrangement [Abstract]
Share-Based Compensation	Share-Based Compensation Under the terms of the Company’s stockholder-approved share-based plans, performance restricted stock units (“PRSUs”), incentive and non-qualified stock options and restricted stock have been, and may be, issued to the Company’s officers, management-level employees and members of its Board of Directors. Stock options granted prior to 2018 generally vest at a rate of one-fourth on each of the first four anniversaries of the grant date and have a maximum contractual term of seven years. Beginning in 2018, stock options granted generally vest at a rate of one-third on each of the first three anniversaries of the grant date and have a maximum contractual term of ten years. Restricted stock granted to employees prior to 2018 generally vests four years after the grant date (cliff vesting) and is subject to accelerated vesting due to certain events, including doubling of the grant price of the Company’s common stock as of the close of business during any five consecutive trading days. Beginning in 2018, restricted stock granted to employees generally vests one-third on each of the first three anniversaries of the grant date. Restricted stock granted to non-employee directors generally vests two years after the grant date (cliff vesting) and is subject to accelerated vesting due to certain events, including doubling of the grant price of the Company’s common stock as of the close of business during any five consecutive trading days. Total share-based compensation expense was as follows: Three Months Ended Nine Months Ended 2020 2019 2020 2019 (In thousands) Stock option expense $ 3,331 $ 3,214 $ 10,330 $ 9,594 Restricted stock expense 4,537 3,995 12,665 11,112 PRSU expense 2,957 6,349 6,883 8,298 Total pre-tax expense $ 10,825 $ 13,558 $ 29,878 $ 29,004 Pre-tax share-based compensation expense is included in the consolidated statement of income in either Cost of sales or Selling, general and administrative expenses, depending on where the recipient’s cash compensation is reported. The fair value of each stock option grant is estimated on the grant date using a Black-Scholes-Merton option pricing model. The following weighted average assumptions were used in the Black-Scholes-Merton model to estimate the fair values of stock options granted during the periods indicated: Nine Months Ended Year Ended December 31, Expected volatility 22.2 % 19.1 % Expected term (years) 5.0 5.0 Risk-free interest rate 0.52 % 2.25 % Expected dividend yield 1.14 % 0.66 % Black-Scholes-Merton fair value per stock option granted $ 11.01 $ 16.85 Expected volatility is based on the historical volatility of the Company’s stock over the stock options’ expected term. 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. The following is a summary of the Company’s stock option activity and related information: Shares Weighted Weighted Aggregate (In thousands) (Years) (In millions) Outstanding at December 31, 2019 4,303 $ 62.50 Granted 963 63.37 Exercised (697) 53.71 Forfeited (114) 71.27 Outstanding at September 30, 2020 4,455 $ 63.84 5.8 $ 158.4 Exercisable at September 30, 2020 2,540 $ 59.31 4.0 $ 101.8 The aggregate intrinsic value of stock options exercised during the nine months ended September 30, 2020 was $37.4 million. The total fair value of stock options vested during the nine months ended September 30, 2020 was $12.9 million. As of September 30, 2020, there was approximately $17.4 million of expected future pre-tax compensation expense related to the 1.9 million non-vested stock options outstanding, which is expected to be recognized over a weighted average period of approximately 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. The following is a summary of the Company’s non-vested restricted stock activity and related information: Shares Weighted (In thousands) Non-vested restricted stock outstanding at December 31, 2019 561 $ 72.46 Granted 242 63.79 Vested (191) 72.21 Forfeited (36) 75.28 Non-vested restricted stock outstanding at September 30, 2020 576 $ 68.72 The total fair value of restricted stock vested during the nine months ended September 30, 2020 was $13.8 million. As of September 30, 2020, there was approximately $24.6 million of expected future pre-tax compensation expense related to the 0.6 million non-vested restricted shares outstanding, which is expected to be recognized over a weighted average period of approximately two years. In March 2020, the Company granted PRSUs to officers and certain key management-level employees an aggregate target award of approximately 119,000 shares of its common stock. The PRSUs vest over a period up to three years from the grant date based on continuous service, with the number of shares earned (0% to 200% of the target award) depending upon the extent to which the Company achieves certain financial and market performance targets measured over the period from January 1, 2020 through December 31, 2022. Half of the PRSUs were valued in a manner similar to restricted stock as the financial targets are based on the Company’s operating results, which represents a performance condition. The grant date fair value of these PRSUs are recognized as compensation expense over the vesting period based on the probable number of awards to vest at each reporting date. The other half of the PRSUs were valued using a Monte Carlo model as the performance target is related to the Company’s total shareholder return compared to a group of peer companies, which represents a market condition. The Company recognizes the grant date fair value of these awards as compensation expense ratably over the vesting period. Total PRSUs outstanding at September 30, 2020 were approximately 264,000.

Commitments and Contingencies Disclosure [Abstract]
Contingencies	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 as defined by federal and state laws and regulations. At September 30, 2020, the Company is named a Potentially Responsible Party (“PRP”) at 13 non-AMETEK-owned former waste disposal or treatment sites (the “non-owned” sites). The Company is identified as a “de minimis” party in 12 of these sites based on the low volume of waste attributed to the Company relative to the amounts attributed to other named PRPs. In eight of these sites, the Company has reached a tentative agreement on the cost of the de minimis settlement to satisfy its obligation and is awaiting executed agreements. The tentatively agreed-to settlement amounts are fully reserved. In the other four sites, the Company is continuing to investigate the accuracy of the alleged volume attributed to the Company as estimated by the parties primarily responsible for remedial activity at the sites to establish an appropriate settlement amount. At the remaining site where the Company is a non-de minimis PRP, the Company is participating in the investigation and/or related required remediation as part of a PRP Group and reserves have been established to satisfy the Company’s expected obligations. The Company historically has resolved these issues within established reserve levels and reasonably expects this result will continue. In addition to these non-owned sites, the Company has an ongoing practice of providing reserves for probable remediation activities at certain of its current or previously owned manufacturing locations (the “owned” sites). For claims and proceedings against the Company with respect to other environmental matters, reserves are established once the Company has determined that a loss is probable and estimable. This estimate is refined as the Company moves through the various stages of investigation, risk assessment, feasibility study and corrective action processes. In certain instances, the Company has developed a range of estimates for such costs and has recorded a liability based on the best estimate. It is reasonably possible that the actual cost of remediation of the individual sites could vary from the current estimates and the amounts accrued in the consolidated financial statements; however, the amounts of such variances are not expected to result in a material change to the consolidated financial statements. In estimating the Company’s liability for remediation, the Company also considers the likely proportionate share of the anticipated remediation expense and the ability of the other PRPs to fulfill their obligations. Total environmental reserves at September 30, 2020 and December 31, 2019 were $30.3 million and $28.9 million, respectively, for both non-owned and owned sites. For the nine months ended September 30, 2020, the Company recorded $6.0 million in reserves. Additionally, the Company spent $4.5 million on environmental matters and the reserve decreased $0.1 million due to foreign currency translation for the nine months ended September 30, 2020. The Company’s reserves for environmental liabilities at September 30, 2020 and December 31, 2019 included reserves of $7.8 million and $9.0 million, respectively, for an owned site acquired in connection with the 2005 acquisition of HCC Industries (“HCC”). The Company is the designated performing party for the performance of remedial activities for one of several operating units making up a Superfund site in the San Gabriel Valley of California. The Company has obtained indemnifications and other financial assurances from the former owners of HCC related to the costs of the required remedial activities. 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.

Restructuring and Related Activities [Abstract]
Realignment Costs	Realignment Costs During the nine months ended September 30, 2020, the Company recorded pre-tax realignment costs totaling $43.9 million, which had the effect of reducing net income by $33.6 million ($0.15 per diluted share). The realignment costs were reported in the consolidated statement of income as follows: $43.7 million in Cost of sales and $0.2 million in Selling, general and administrative expenses. The realignment costs were reported in segment operating income as follows: $22.8 million in EIG, $20.9 million in EMG. The realignment actions primarily related to a reduction in workforce and asset write-downs, primarily inventory, in response to the weak global economy as a result of the COVID-19 pandemic. The realignment activities have been broadly implemented across the Company’s various businesses with substantially all actions expected to be completed by end of 2020. Accrued liabilities and other in the Company’s consolidated balance sheet included amounts related to the first quarter of 2020 realignment costs as follows (in millions): Balance at December 31, 2019 $ — Pre-tax charges 43.9 Utilization (19.0) Balance at September 30, 2020 $ 24.9

Accounting Changes and Error Corrections [Abstract]
Basis of Presentation	The accompanying consolidated financial statements are unaudited. AMETEK, Inc. (the “Company”) believes that all adjustments (which primarily consist of normal recurring accruals) necessary for a fair presentation of the consolidated financial position of the Company at September 30, 2020, the consolidated results of its operations for the three and nine months ended September 30, 2020 and 2019 and its cash flows for the nine months ended September 30, 2020 and 2019 have been included. Quarterly results of operations are not necessarily indicative of results for the full year. The accompanying consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes presented in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019 as filed with the U.S. Securities and Exchange Commission.
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements Effective January 1, 2020, the Company adopted ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), using the modified retrospective transition method. ASU 2016-13 provides guidance on the estimation of current expected credit losses on financial instruments, including trade receivables. ASU 2016-13 requires entities to consider a broad range of information to estimate expected credit losses, including increased forward-looking information, which may result in earlier recognition of losses when compared to prior standards. The adoption of ASU 2016-13 In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (“ASU 2018-13”), which changes the fair value measurement disclosure requirements of ASC Topic 820, Fair Value Measurement (“ASC 820”), by eliminating, modifying and adding to those requirements. ASU 2018-13 also modifies the disclosure objective paragraphs of ASC 820 to eliminate (1) “at a minimum” from the phrase “an entity shall disclose at a minimum” and (2) other similar “open ended” disclosure requirements to promote the appropriate exercise of discretion by entities. The Company prospectively adopted ASU 2018-13, effective January 1, 2020, and the adoption did not have a significant impact on the Company’s consolidated results of operations, financial position, cash flows and financial statement disclosures. In August 2018, the FASB issued ASU No. 2018-15, Intangibles–Goodwill and Other–Internal-Use Software (“ASU 2018-15”), that requires implementation costs incurred by customers in cloud computing arrangements to be deferred and recognized over the term of the arrangement, if those costs would be capitalized by the customer in a software licensing arrangement under the internal-use software guidance in ASC Topic 350, Intangibles–Goodwill and Other. ASU 2018-15 requires a customer to disclose the nature of its hosting arrangements that are service contracts and provide disclosures as if the deferred implementation costs were a separate, major depreciable asset class. The Company prospectively adopted ASU 2018-15, effective January 1, 2020, and the adoption did not have a significant impact on the Company’s consolidated results of operations, financial position, cash flows and financial statement disclosures. Recent Accounting Pronouncements In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”), which simplifies the accounting for income taxes by removing certain exceptions to the general principles in ASC Topic 740. ASU 2019-12 is effective for fiscal years beginning after December 15, 2021. Early adoption is permitted and the amendments in this ASU should be applied on a retrospective basis to all periods presented. The Company has not determined the impact ASU 2019-12 may have on the Company’s consolidated results of operations, financial position, cash flows or financial statement disclosures. In August 2018, the FASB issued ASU No. 2018-14, Compensation–Retirement Benefits–Defined Benefit Plans–General (“ASU 2018-14”), which changes the disclosure requirements of ASC Topic 715, Compensation – Retirement Benefits, by eliminating, modifying and adding to those requirements. ASU 2018-14 is effective for fiscal years beginning after December 15, 2020. Early adoption is permitted and the amendments in this ASU should be applied on a retrospective basis to all periods presented. The Company has not determined the impact ASU 2018-14 may have on the Company’s consolidated financial statement disclosures.
Accounts Receivable	Accounts Receivable The Company maintains allowances for estimated losses resulting from the inability of customers to meet their financial obligations to the Company. The Company recognizes an allowance for doubtful accounts, on all accounts receivable, which considers the length of time receivables are past due, customers’ billing exposure, ability to pay, and contract terms. The Company also considers general and market business conditions, country, and political risk. Balances are written off when determined to be uncollectible. At September 30, 2020, the Company recorded $614.8 million of accounts and notes receivable, net of allowances of $12.6 million. Changes in the allowance were not material for the three and nine months ended September 30, 2020.
