UNSPSC 41111924: Oxygen sensors

UNSPSC 41111924 Oxygen sensors, a Commodity code, encompasses sensor components and monitoring equipment for detecting and managing dissolved oxygen, hazardous gases, and environmental conditions across municipal wastewater treatment, water services, and laboratory operations. State and local governments solicit oxygen sensors and integrated sensor-controller systems as part of broader procurements for facility operations, equipment replacement, and infrastructure compliance. The code appears primarily in municipal utilities and environmental agencies managing wastewater treatment systems, water quality monitoring, and laboratory facilities. Issuing bodies include county school districts, municipal wastewater treatment facilities, municipal water services departments, and state environmental protection agencies. Equipment purchased includes oxygen controllers and sensors with mounting hardware installed at wastewater treatment plants, atmospheric monitoring sensors for detecting hydrogen sulfide, methane, oxygen depletion, and other hazardous gases at water and wastewater lift stations and confined spaces, and environmental monitoring systems for laboratory equipment such as refrigerators, freezers, incubators, and drying ovens.

Recent activity spans Connecticut, Arizona, Illinois, and Georgia. The Town of Glastonbury, Connecticut issued IFB GL202717 for replacement and installation of oxygen controllers and sensors at its Wastewater Treatment Facility, with bids due October 6, 2026. The City of Phoenix Water Services Department solicited sealed offers for atmospheric monitoring instruments—fixed installations under IFB-27-0435 due September 4, 2026, specifying sensors, controllers, alarms, and accessories for hydrogen sulfide, methane, and oxygen depletion detection across lift stations, headworks buildings, and confined spaces, with a five-year contract term. The Georgia Department of Agriculture Laboratory Division issued RFQ 40200ERFQ0018662027 for an environmental conditions monitoring system to monitor temperature and humidity across fifty-eight critical laboratory units in Tifton and Atlanta, with responses due August 21, 2026. Clayton County Public Schools in Georgia issued IFB 002-27 for musical equipment and sound systems due November 5, 2026, though this procurement appears misclassified under the oxygen sensors code and does not reflect genuine activity in the commodity.
