UNSPSC 41113104: Explosimeters

UNSPSC 41113104 Explosimeters is a Commodity code that maps poorly to the recent state and local solicitations bearing this tag. The code nominally describes hand-held or portable gas-detection instruments used to measure explosive or combustible-vapor concentrations in air. However, the recent opportunities posted under this code span analytical laboratory equipment (thermal and gas analysis systems), wastewater methane detection infrastructure and maintenance, instructional resources for career and technical education, medical oxygen supply, lab information management software, particulate matter monitoring devices, landfill gas consulting, and digester gas utilization projects—none of which fit the explosimeter scope. The sole opportunity with direct relevance to gas detection is the Orange County Transportation Authority's IFB 250322 for methane detection system service and maintenance across five transit facilities, which involves calibration, testing, and repair of SEC-3100 sensors, General Monitor IR5000 open-path hydrocarbon gas monitors, and Sierra Monitor gas detection units over a four-year term with an estimated value of $260,000. Aside from OCTA's methane work, the code shows little recent activity aligned with explosimeter procurement.

No discernible pattern of repeat buyers, geographic concentration, or issuing-body type emerges from these opportunities because the code itself appears to be a cataloging artifact rather than a category driving substantive procurement. The opportunities span a university (University of Wisconsin-Madison), a regional transit authority (Orange County Transportation Authority in California), a school district (Klein Independent School District in Texas), city governments (Tampa, Detroit, Fort Worth), county agencies (Santa Clara County, Greenville County in South Carolina), and a municipal water district (Eastern Municipal Water District in California)—representing no particular sector or buying pattern. If your firm specializes in portable gas detection, sensor calibration, or methane monitoring infrastructure for transportation facilities, OCTA's 2026 service contract represents a concrete near-term opportunity; for all other explosimeter-adjacent work, this code appears misaligned with actual procurement activity and warrants re-tagging at the source.
