UNSPSC 41113113: Sulfur dioxide analyzers or detectors

UNSPSC 41113113 Sulfur dioxide analyzers or detectors is a Commodity code, but recent state and local opportunities show negligible alignment with the code's nominal scope. Of nine recent solicitations tagged to this code, only one—the City of Phoenix's IFB 27-0435 for atmospheric monitoring instruments—directly addresses hazardous-gas detection equipment. The Phoenix opportunity seeks sensors and controllers to detect hydrogen sulfide, methane, oxygen depletion, chlorine, ammonia, ozone, chlorine dioxide, and carbon monoxide at water and wastewater facilities; sulfur dioxide detection is not explicitly mentioned. The remaining eight opportunities span medical-grade oxygen supply (Collier County Emergency Medical Services), refrigerant extraction (City of Tucson), waste-to-energy facility design-build-operate-maintain contracting (Solid Waste Authority of Palm Beach County), compressor gas cooler equipment purchases (City of Austin, twice), hydrogen sulfide corrosion control service (City of Orlando), thermal and gas analysis laboratory equipment (University of Wisconsin-Madison), and methane detection system maintenance (Orange County Transportation Authority). The code shows little recent activity specifically targeting sulfur dioxide analyzers or detectors as standalone products or services.

Issuing bodies posting under this code include cities (Phoenix, Tucson, Orlando, Austin), counties (Collier County, Gwinnett County), a special-purpose transit authority (Orange County Transportation Authority), a solid waste authority, and a university. Geographic spread spans Florida (Collier County, Palm Beach County, Orange County, Orlando), Arizona (Phoenix, Tucson), Georgia (Gwinnett County, though without substantive opportunity detail), Texas (Austin), and Wisconsin. The one substantially relevant recent opportunity is the City of Phoenix Water Services Department's five-year IFB 27-0435, due September 4, 2026, for atmospheric monitoring instruments—fixed installations including sensors, controllers, alarms, calibration, and replacement parts, with a pre-offer conference scheduled August 25, 2026 and DBE-Neutral participation requirements under Federal Transit Administration guidelines. The Orange County Transportation Authority's prevailing-wage IFB 250322 for methane detection system service and maintenance, due June 1, 2026 with an estimated value of $260,000 over four years, also relates tangentially to gas-detection work but does not address sulfur dioxide detection specifically.
