UNSPSC 41111938: Level sensors or transmitters

UNSPSC 41111938 Level sensors or transmitters is a Commodity code that encompasses fixed and portable monitoring instruments for detecting hazardous gases, measuring environmental conditions in laboratory and industrial settings, and supporting infrastructure asset inspection — work that state and local governments procure to maintain operational safety and regulatory compliance across water systems, wastewater facilities, environmental laboratories, and utility operations. The work solicited under this code includes atmospheric monitoring systems for confined spaces and hazardous-gas detection at water and wastewater treatment facilities, environmental conditions monitoring systems for laboratory equipment, and related installation, training, calibration, and parts support. Issuing bodies span state environmental agencies (Illinois EPA, Georgia Department of Agriculture), municipal utilities (City of Phoenix Water Services Department, City of Atlanta Department of Watershed Management), school districts (Clayton County Public Schools), and university systems (Texas A&M University System), with state and local environmental protection departments and water utilities appearing as repeat buyers seeking compliance and safety monitoring infrastructure.

Recent activity concentrates in the Southeast and Southwest, with Georgia, Illinois, Arizona, and Texas showing current solicitation volume. The Georgia Department of Agriculture Laboratory Division issued an RFQ on August 7, 2026 for an environmental conditions monitoring system to replace aging equipment across facilities in Tifton and Atlanta, with responses due August 21, 2026. The City of Phoenix Water Services Department posted IFB 27-0435 on August 14, 2026, soliciting atmospheric monitoring instruments—fixed installations for hydrogen sulfide, methane, oxygen depletion, and other hazardous gases at water and wastewater facilities, with offers due September 4, 2026 and a pre-offer conference scheduled for August 25, 2026; the five-year contract requires DBE-N compliance and local parts inventory within 48 hours. The Illinois EPA issued multiple bids in August 2026 for laboratory-grade analytical equipment including ozone transfer standards and zero air generators (IFB due August 27, 2026). Note that Clayton County Public Schools' IFB 002-27, posted October 1, 2026, for musical equipment and sound systems appears to have been miscoded under this UNSPSC — the procurement is unrelated to level sensors or transmitters.
