UNSPSC 41113124: Respirometer

A type of device that is designed to measure the discharge gases, such as carbon gas, that are released to outside of body for certain time, periodically or consecutively through the chemical change of substance within the body and building up the oxygen volume supplied from outside to sustain the plant or animal life.

UNSPSC 41113124 Respirometer is a Commodity code that encompasses measurement and monitoring equipment used to detect and analyze gases in confined spaces, wastewater treatment environments, and industrial facilities. State and local governments procure atmospheric monitoring instruments, gas detection sensors, hydrogen sulfide control systems, and related calibration and maintenance services under this code. The issuing bodies soliciting under the code include municipal utilities (wastewater and water services departments), county emergency services, transportation authorities, and specialized public districts. Collier County Emergency Medical Services, the City of Orlando, the City of Phoenix Water Services Department, and the Orange County Transportation Authority appear as recent active buyers. The work being solicited ranges from medical-grade oxygen supply and tank rental for first responders to sophisticated fixed atmospheric monitoring systems detecting multiple hazard gases (hydrogen sulfide, methane, oxygen depletion, chlorine, ammonia, ozone, chlorine dioxide, and carbon monoxide) at lift stations, headworks buildings, and confined spaces. Service components include installation, training, calibration, maintenance, repair parts stocking, and emergency response capabilities.

Recent opportunities cluster in Florida, Arizona, and California. Collier County EMS solicited medical-grade oxygen supply and delivery via IFQ with a response date of October 1, 2026, anticipating approximately $12,000 annual spending. The City of Phoenix Water Services Department issued IFB-27-0435 for atmospheric monitoring instruments-fixed (hydrogen sulfide, methane, and multiple other gases) at water and wastewater facilities, with a five-year contract term and offers due September 4, 2026; the pre-offer conference was scheduled for August 25, 2026. The Orange County Transportation Authority issued IFB 250322 for methane detection system service and maintenance across five facilities under a prevailing wage contract, with a $260,000 estimated value over four years and bids due June 1, 2026; Addendum #2 Revision was issued May 19, 2026. The City of Orlando solicited hydrogen sulfide control service via IFB 260556 at three lift stations with proposals due September 9, 2026. A University of Wisconsin-Madison bid for a Simultaneous Thermal and Gas Analysis System closed July 17, 2026, though this represents higher-education research procurement rather than core state and local government operations.
