UNSPSC 41113123: Smoke tester

A tester that measures the volume of smoke generated from the process of experimenting the chemical reaction in a laboratory.

UNSPSC 41113123 Smoke tester (Commodity) encompasses gas detection, measurement, and monitoring equipment that state and local governments procure for environmental, occupational safety, and utility operations — though the recent solicitations tagged under this code show minimal alignment with smoke-specific testing and instead reflect broader atmospheric monitoring, gas extraction, and gas control applications. Issuing bodies soliciting under or adjacent to this code span water and wastewater utilities, emergency medical services, environmental divisions, transportation authorities, and municipal energy facilities. Cities and counties dominate the buyer base, with transit authorities and special-purpose districts appearing occasionally; the Orange County Transportation Authority and the City of Phoenix appear as recent purchasers of gas detection systems, while the Solid Waste Authority of Palm Beach County and Collier County Emergency Medical Services represent waste-to-energy and emergency response sectors. The geographic footprint includes California, Florida, Arizona, Texas, Georgia, and Wisconsin, reflecting dispersed regional demand rather than concentration in a single jurisdiction.

Representative recent opportunities illustrate the code's actual buying patterns. The City of Phoenix Water Services Department issued IFB 27-0435 (atmospheric monitoring instruments, sealed offers due September 4, 2026) to procure fixed sensors and controllers for hydrogen sulfide, methane, oxygen depletion, chlorine, ammonia, ozone, chlorine dioxide, and carbon monoxide detection at lift stations and wastewater facilities, a five-year firm-fixed-price contract with DBE participation requirements. The Orange County Transportation Authority solicited IFB 250322 (methane detection system service and maintenance, bids due June 1, 2026) for triannual calibration, testing, and parts replacement across five transit bases at an estimated four-year value of $260,000 under prevailing wage and Davis-Bacon terms. Collier County Emergency Medical Services issued an RFQ (QQ2026152, quotes due October 8, 2026) for medical-grade oxygen supply in multiple cylinder sizes with tank rental, hydrostatic testing, and emergency delivery — a use case that sits outside the detector/tester taxonomy but reflects procurement tagged under this code. The City of Tucson Environmental and General Services Division posted RFP 240011 for EPA-certified refrigerant reclamation services (proposals due September 19, 2024) involving gas extraction from approximately 50 units per week. Solicitations show modest volume but recurring demand for detection and gas-handling capability certifications, compliance with EPA and OSHA standards, and ability to support emergency response or routine utility operations.
