Organization, Consolidation, Basis of Presentation, Business Description and Accounting Policies [Text Block]	Note 1 – Condensed Consolidated Financial Statements The condensed consolidated balance sheet as of September 30, 2016, the condensed consolidated statements of income and comprehensive income, for the three and nine-months ended September 30, 2016 and 2015 have been prepared in accordance with accounting principles generally accepted in the United States of America. These interim unaudited condensed consolidated financial statements reflect all adjustments which are, in the opinion of management, necessary to fairly present the financial position, results of operations and cash flows at September 30, 2016, and for all periods presented. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted. Certain amounts have been reclassified from the prior year presentation to conform to the current year presentation. The results of operations for the three and nine-month period ended September 30, 2016 are not necessarily indicative of operating results for the full year. It is suggested that these condensed consolidated financial statements be read in conjunction with the consolidated financial statements and notes included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2015, previously filed with the Securities and Exchange Commission. MOCON Inc. and its subsidiaries, develops, manufacturers and markets measurement, analytical, monitoring and consulting services for customers in the barrier packaging, food, pharmaceutical, consumer products, industrial hygiene, environmental, air quality monitoring, oil and gas exploration and other industries throughout the world. We report our operating segments as Package Testing Products and Services (“Package Testing”), Permeation Products and Services (“Permeation”), and Industrial Analyzers Products and Services and Other (“Industrial Analyzers and Other”) for financial reporting purposes. Principles of Consolidation The consolidated financial statements include our accounts and our wholly-owned subsidiaries. All material intercompany balances and transactions have been eliminated in consolidation. Revision to previously issued unaudited quarterly financial information The Company discovered the elimination of intercompany revenue and the related gross profit related to our Permeation Products and Services reporting segment was incorrectly recognized for the three months ended September 30, 2015. We assessed the impact of the error and concluded that it was not material to any of its previously issued financial statements; however, we have chosen to correct the misstatement by revising our previously issued unaudited three months ended September 30, 2015 Consolidated Statement of Operations. The revision had no impact to gross profit, operating income, earnings per share, Consolidated Balance Sheet or Consolidated Statement of Cash Flows. The impact of the misstatement of previously reported revenue and cost of sales was $470,000. The following table represents the effects of the revisions for the three months ended September 30, 2015. Future filings of Form 10-K will reflect the revisions noted below. As Previously Reported Effect of Revision As Revised Three Months Ended September 30, 2015 Total revenue $ 15,492 $ (470 ) $ 15,022 Total cost of revenue 7,174 (470 ) 6,704 Gross profit 8,318 - 8,318 As Previously Reported Effect of Revision As Revised Nine Months Ended September 30, 2015 Total revenue $ 45,901 $ (470 ) $ 45,431 Total cost of revenue 21,079 (470 ) 20,609 Gross profit 24,822 - 24,822

Disposal Groups, Including Discontinued Operations, Disclosure [Text Block]	Note 2 – Sale of Business On January 14, 2016, we entered into an Asset Purchase Agreement, as amended on May 18, 2016 (the “Agreement”) with Volatile Analysis Corporation (“VAC”) pursuant to which we agreed to sell to VAC the assets exclusively used in our business of providing equipment and analytical chemistry services and related formulation, product development, and consulting services, primarily focused on identification of odors and aromas. This business was included in our Permeation segment and conducted from our Round Rock, Texas facility. The purchase and sale of the assets was finalized and closed on May 18, 2016. We received proceeds of $500,000 resulting in a realized gain of $352,000, which is included in other income (expense), net on the consolidated income statement. The remaining $800,000 owed by VAC in accordance with the Agreement will be recognized on the cost recovery method upon receipt. This business does not qualify for discontinued operations or available for sale treatment since it does not represent a strategic shift that had or will have a major effect on our operations and financial results.

Notes to Financial Statements
Earnings Per Share [Text Block]	Note 4 – Net Income Per Common Share Basic net income per common share is computed by dividing net income by the weighted average number of shares of common stock outstanding during the period. Diluted net income per common share is computed using the treasury stock method to compute the weighted average common stock outstanding assuming the conversion of potential dilutive common shares. The following table presents a reconciliation of the denominators used in the computation of net income per common share – basic, and net income per common share – diluted, for the three and nine-months ended September 30, 2016 and 2015 (expressed in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2016 2015 2016 2015 Weighted shares of common stock outstanding - basic 5,823 5,753 5,769 5,748 Dilutive impact of share-based awards 36 55 24 78 Weighted shares of common stock outstanding - diluted 5,859 5,808 5,793 5,826 Outstanding stock options totaling 382,969 and 431,560 for the three-months ended September 30, 2016 and September 30, 2015, respectively, and 595,435 and 316,310 for the nine-months ended September 30, 2016 and September 30, 2015, respectively, were excluded from the net income per common share calculation because the shares would be anti-dilutive.

Restructuring and Related Activities Disclosure [Text Block]	Note 9 – Realignment Expenses During 2015, we implemented a Realignment Plan in order to simplify our business structure by reducing the number of legal entities and by combining the sales and marketing teams of our Package Testing and Permeation segments under common leadership. As of December 31, 2015, approximately $483,000 was included in Accrued Compensation and related expenses and approximately $137,000 was included in Accounts payable on the consolidated balance sheet. During the nine months ended September 30, 2016, management concluded to eliminate the chief operating officer position and a divisional executive position in addition to other personnel changes. As a result, $153,000 and $903,000 of realignment expenses were recognized during the three and nine-months ended September 30, 2016. Amounts accrued, realignment expense and cash payments for the three and nine-months ended September 30, 2016 and September 30, 2015 were as follows (expressed in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2016 2015 2016 2015 Beginning Balance $ 806 $ 128 $ 620 $ - Realignment Expense 153 190 903 318 Cash Payments (166 ) (182 ) (730 ) (182 ) Ending Balance $ 793 $ 136 $ 793 $ 136 As of September 30, 2016, approximately $793,000 is included in Accrued compensation and related expenses on the consolidated balance sheet and is expected to be paid throughout the end of 2017.

Income Tax Disclosure [Text Block]	Note 10 – Income Taxes Our provision for income tax expense was 23 percent and 27 percent of income before income taxes for the three-months ended September 30, 2016 and September 30, 2015 respectively. Our provision for income tax expense was 27 percent and 31 percent of income before income taxes for the nine-months ended September 30, 2016 and September 30, 2015, respectively. The rate in the three and nine-months ended 2016 and 2015 were lower than the statutory rate due primarily to the effect of foreign operations where tax rates tend to be lower, the domestic manufacturing deduction, the research credit and the provision to return discrete items related to returns filed in the three month periods. As of September 30, 2016 and December 31, 2015, the liability for gross unrecognized tax benefits was 126,000 and 187,000, respectively. With the exception of lapsing statutes of limitation it is expected that the amount of unrecognized tax benefits for positions which we have identified is not expected to materially change in the next twelve months.

Disclosure of Compensation Related Costs, Share-based Payments [Text Block]	Note 11 – Share-Based Compensation Stock Option Plans As of September 30, 2016, we have reserved 388,082 shares of common stock for options and other share-based incentive awards that are still available for grant under our 2015 stock incentive plan, and 714,585 shares for options that have been granted under either the 2006 or 2015 stock incentive plan. We issue new shares of common stock upon exercise of stock options. Amounts recognized in the condensed consolidated financial statements related to share-based compensation are as follows (expressed in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2016 2015 2016 2015 Total cost of share-based compensation $ 185 $ 167 $ 561 $ 488 Amount of income tax benefit recognized in earnings (25 ) (20 ) (30 ) (81 ) Amount charged against net income $ 160 $ 147 $ 531 $ 407 The fair value of each option grant is estimated on the date of grant using the Black-Scholes option-pricing model. We use historical data to estimate the expected price volatility, expected option life and expected forfeiture rate. Our estimates are based on expected volatility for awards granted on daily historical trading data of our common stock for a period equivalent to the expected term of the award. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for the estimated life of the option. We estimate the expected term consistent with historical exercise and cancellation activity of its previous share-based grants with a seven or ten year as applicable contractual term. Forfeitures are based on historical experience. The dividend yield is calculated based upon the dividend payments made during the prior four quarters as a percent of the average stock price for that period. A summary of the option activity for the first nine months of 2016 is as follows (expressed in thousands, except share and per share amounts): Weighted Weighted Average Aggregate Average Remaining Intrinsic Exercise Contractual Value Shares Price Term (in thousands) Options outstanding, December 31, 2015 797,378 $ 14.91 4.55 $ 453 Granted 20,000 $ 14.42 Exercised (57,050 ) $ 15.27 146 Cancelled or expired (45,743 ) $ 13.61 Options outstanding, September 30, 2016 714,585 $ 14.99 3.89 779 Options exercisable, September 30, 2016 452,160 $ 14.99 3.05 519 The total intrinsic value of options exercised was $135,000 and $6,000 during the three-months ended September 30, 2016 and September 30, 2015, respectively, and $146,000 and $189,000 during the nine-months ended September 30, 2016 and September 30, 2015, respectively. As of September 30, 2016, there was $388,000 of total unrecognized compensation cost related to unvested share-based compensation granted under our plans. That cost is expected to be recognized over a weighted-average period of .9 years. The total fair value of option shares vested during the three-months ended September 30, 2016 and September 30, 2015 was $56,000 and $88,000, respectively and $56,000 and $264,000 during the nine-months ended September 30, 2016 and September 30, 2015, respectively. Employee Stock Purchase Plan On May 27, 2015, our shareholders approved the 2015 Employee Stock Purchase Plan (“Purchase Plan”) whereby 50,000 shares of common stock were made available for sale under the plan. The first offering period began on January 1, 2016 and provides participants an option to purchase shares of our common stock at a price per share equal to 85 percent of the value of the share of common stock at the beginning or end of the offering period (whichever is less). For the offering period ended June 30, 2016, 1,803 shares were purchased under the plan. The second offering period began on July 1, 2016, and will close on December 31, 2016

Segment Reporting Disclosure [Text Block]	Note 12 – Segments We have four operating segments, structured by differences in products and services, that are regularly reviewed by our chief operating decision maker to make decisions about allocating resources and assessing segment performance. The segment performance is evaluated at segment operating income which is defined as gross profit less selling, general and administrative expenses and research and development expenses. General corporate expenses, including costs associated with various support functions such as human resources, information technology, finance and accounting, and general and administrative costs, are allocated to the reportable segments primarily on the basis of segment gross margin. Our four operating segments have been aggregated into three reportable segments. We aggregated our Other Products and Services operating segment into the Industrial Analyzers Products and Services segment based on minimal business activity and materiality. The Package Testing segment provides customers with the ability to assess package performance, shelf-life, package improvement, cost reduction, sustainability and product safety using Modified Atmosphere Packaging and other technologies. The Permeation segment includes instruments and services that measure the rate at which various gases and vapors permeate through a variety of materials. The Industrial Analyzers and Other segment includes advanced gas analysis and monitoring instrumentation used in applications such as oil and gas exploration, beverage and specialty gas analysis, industrial hygiene and safety, food safety, environmental air monitoring and homeland security. The accounting policies of the reportable segments are the same as those described in Note 1 to the Consolidated Financial Statements found in our Annual Report on Form 10-K for the fiscal year ended December 31, 2015. Intersegment revenue for the three and nine-months ended September 30, 2016 and September 30, 2015 were insignificant. Financial information by reportable segment for the three and nine-months ended September 30, 2016 and September 30, 2015 is as follows (expressed in thousands): Package Testing Permeation Industrial Analyzers and Other Unallocated - Corporate Consolidated Three Months Ended September 30, 2016 Revenue $ 7,572 $ 6,343 $ 2,145 $ - $ 16,060 Gross profit 4,434 3,859 905 - 9,198 Operating Income (Loss) 1,561 1,545 (373 ) (153 ) 2,580 Three Months Ended September 30, 2015 Revenue $ 6,454 $ 6,012 $ 2,556 $ - $ 15,022 Gross profit 3,553 3,574 1,191 - 8,318 Operating Income (Loss) 982 1,112 (280 ) (190 ) 1,624 Nine Months Ended September 30, 2016 Revenue $ 21,903 $ 17,110 $ 7,408 $ - $ 46,421 Gross profit 12,578 10,150 3,345 26,073 Operating Income (Loss) 3,104 2,874 (879 ) (903 ) 4,196 Nine Months Ended September 30, 2015 Revenue $ 19,684 $ 18,080 $ 7,667 $ - $ 45,431 Gross profit 10,703 10,562 3,557 - 24,822 Operating Income (Loss) 2,424 2,935 (1,214 ) (318 ) 3,827

Accounting Policies [Abstract]
Consolidation, Policy [Policy Text Block]	Principles of Consolidation The consolidated financial statements include our accounts and our wholly-owned subsidiaries. All material intercompany balances and transactions have been eliminated in consolidation.
Error Corrections and Prior Period Adjustments [Policy Text Block]	Revision to previously issued unaudited quarterly financial information The Company discovered the elimination of intercompany revenue and the related gross profit related to our Permeation Products and Services reporting segment was incorrectly recognized for the three months ended September 30, 2015. We assessed the impact of the error and concluded that it was not material to any of its previously issued financial statements; however, we have chosen to correct the misstatement by revising our previously issued unaudited three months ended September 30, 2015 Consolidated Statement of Operations. The revision had no impact to gross profit, operating income, earnings per share, Consolidated Balance Sheet or Consolidated Statement of Cash Flows. The impact of the misstatement of previously reported revenue and cost of sales was $470,000. The following table represents the effects of the revisions for the three months ended September 30, 2015. Future filings of Form 10-K will reflect the revisions noted below. As Previously Reported Effect of Revision As Revised Three Months Ended September 30, 2015 Total revenue $ 15,492 $ (470 ) $ 15,022 Total cost of revenue 7,174 (470 ) 6,704 Gross profit 8,318 - 8,318 As Previously Reported Effect of Revision As Revised Nine Months Ended September 30, 2015 Total revenue $ 45,901 $ (470 ) $ 45,431 Total cost of revenue 21,079 (470 ) 20,609 Gross profit 24,822 - 24,822
