UNSPSC 41113117: Single gas monitors

UNSPSC 41113117 Single gas monitors (Commodity) encompasses calibration, repair, and maintenance services for portable and fixed gas detection equipment, along with refill and supply of specialty and medical gases used by state and local agencies for workplace safety, environmental monitoring, and emergency response. State and local governments procure these services across multiple operational contexts: portable monitor calibration and sensor replacement for transportation departments and public safety agencies; fixed atmospheric monitoring systems for water and wastewater treatment facilities to detect hydrogen sulfide, methane, oxygen depletion, and other hazardous gases; medical-grade oxygen supply and tank management for emergency medical services; and specialty gas refills for environmental and chemistry laboratory operations. Issuing bodies include city departments (Phoenix Water Services, City of Orlando, City of Austin, City of Tucson), county emergency services and transportation authorities (Collier County EMS, Orange County Transportation Authority), state environmental and transportation agencies (California Department of Transportation, California Department of Toxic Substances Control), and specialized districts (Solid Waste Authority of Palm Beach County). Recent solicitations reflect a mix of one-time equipment procurements, service contracts with multi-year terms, and on-demand maintenance agreements.

Recent activity concentrates in California, Florida, Arizona, and Georgia. Caltrans issued IFB 07A6478 in September 2026 for calibration and repair of RKI Instruments portable gas monitors (GX-2012, GX-2009, and Eagle 2 models) at its Pomona location, with bids due October 6, 2026, requiring RKI Instruments authorized dealer certification and a 50-mile radius business location.

The City of Phoenix Water Services solicited atmospheric monitoring instruments for fixed installation at water and wastewater facilities under IFB-27-0435, with offers due September 4, 2026 and a five-year contract term. Collier County Emergency Medical Services in Florida solicited medical-grade oxygen supply and tank management services (QQ2026152) with quotes due October 8, 2026 and annual spending estimated at $12,000.
