UNSPSC 41113104: Explosimeters

UNSPSC 41113104 Explosimeters is a Commodity code that state and local governments buy for hazardous gas detection and measurement equipment, though recent solicitation activity under this code shows substantial scope misalignment. The code nominally describes instruments to measure explosive gas concentrations, yet the opportunities posted under it span medical-grade oxygen supply and rental (Collier County EMS), refrigerant extraction and recovery services (City of Tucson), hydrogen sulfide corrosion and odor control chemical application (City of Orlando), atmospheric monitoring sensors and detection systems for wastewater and water facilities (City of Phoenix), and methane detection system service and maintenance (Orange County Transportation Authority). Only the Phoenix and OCTA opportunities directly relate to gas detection instrumentation; the medical oxygen, refrigerant recovery, and hydrogen sulfide treatment solicitations represent equipment supply or chemical/environmental services rather than explosimeter purchase or deployment.

Issuing bodies include municipal water and wastewater departments (Phoenix, Orlando), county emergency services (Collier County), city environmental divisions (Tucson), and transit authorities (OCTA). Geographic activity spans Florida (Collier County, Orange County, Orlando), Arizona (Tucson, Phoenix), and California (OCTA covers Orange County). The two most directly relevant recent opportunities are the City of Phoenix's August 2026 IFB for atmospheric monitoring instruments-fixed to detect hazardous gases at water and wastewater facilities (due September 4, 2026, five-year term with DBE-Neutral participation required, specifications from manufacturers including ATI, De Nora, Drager, and MSA) and the Orange County Transportation Authority's IFB 250322 for methane detection system service and maintenance across five facilities (due June 1, 2026, estimated contract value $260,000 over four years, prevailing wage and DBE requirements apply). The code shows limited coherent activity; practitioners should verify commodity alignment against actual scope requirements before pursuing opportunities tagged to this code.
