Notes to Financial Statements
Significant Transactions [Text Block]	Note 11. Significant Transaction We completed the previously-announced closure of our Butler, New Jersey facility during the quarter ended June 30, 2021. The facility was primarily used in the production of our gas flow calibration and air sampling equipment, which is part of our Instruments division. Our manufacturing facility in Lakewood, Colorado is currently undergoing renovations that will allow it to accommodate the production of the gas flow calibration and air sampling equipment. Consolidating the production of these products is expected to reduce facilities costs and streamline our use of lean manufacturing tools under central management to further encourage production efficiencies. As a result of the facility consolidation, we incurred $53 of severance costs during the quarter ended June 30, 2021 which were recorded to cost of revenues, selling, and general and administrative expense on the Consolidated Statement of Income. As of June 30, 2021, a total of $156 remained outstanding and accrued, which primarily relates to severance costs. We do not expect to incur any material expenses related to the Butler, New Jersey consolidation in future periods.
