UNSPSC 41111951: Humidistat

Instrument for automatically controlling humidity in steaming cabinets and furnaces.

UNSPSC 41111951 Humidistat is a Commodity code that nominally designates humidity-control sensing devices, but the recent state and local opportunities posted under this code show little alignment with that scope. The opportunities instead span musical equipment and sound systems for school districts, atmospheric gas monitoring instruments for water and wastewater facilities, laboratory analytical equipment including mass spectrometers and calibration standards, environmental conditions monitoring systems for university and state laboratory facilities, and pipeline inspection and sewer cleaning equipment for municipal public works departments. Only one opportunity—the Georgia Department of Agriculture Laboratory Division's August 21, 2026 RFQ for an environmental conditions monitoring system covering fifty-eight critical units across laboratory facilities in Tifton and Atlanta—includes a humidity-monitoring requirement as part of a broader environmental conditions package. The issuing bodies are diverse: state environmental protection and agriculture agencies, county and city public schools, municipal water and wastewater departments, university systems, and special-purpose laboratory divisions. This fragmentation suggests the code carries a broad or misaligned taxonomy assignment rather than a coherent product category.

Recent activity is concentrated in Georgia and Illinois, with additional solicitations in Arizona, Texas, and nationally via university system procurement. Representative opportunities include the Georgia Department of Agriculture's RFQ for environmental monitoring (responses due August 21, 2026); the City of Phoenix Water Services Department's IFB 27-0435 for atmospheric monitoring instruments at water and wastewater facilities (responses due September 4, 2026); the Illinois Environmental Protection Agency's IFB for a Tandem Mass Spectrometer system for pesticide analysis (responses due September 1, 2026); and Clayton County Public Schools' IFB 002-27 for musical equipment and sound systems (responses due November 5, 2026, with a 15 percent Small Local Business Enterprise contracting goal). None of these opportunities center on humidistats or humidity control as a standalone product line. Firms pursuing activity under this code should verify that individual opportunities are correctly tagged and align with their actual service or product scope before investing bid preparation resources.
