UNSPSC 41103417: Indoor air quality monitor

A device that measures several data on indoor environment conservation of buildings in comprehensive terms. It may measure diversely in accordance with the device characteristics, such as indoor temperature, humidity, radiation temperature, wet bulb temperature, wind speed, relative humidity, carbon dioxide, carbon monoxide, dust and others.

UNSPSC 41103417 Indoor air quality monitor is a Commodity code that captures state and local procurement of specialized air quality sensing and monitoring equipment, ranging from integrating nephelometers certified as Federal Equivalent Method instruments to dual-channel canister samplers, ozone precursor monitoring systems, and hydrogen sulfide cavity ringdown spectrometers. Recent solicitations show state environmental agencies, school districts, and municipalities buying high-precision atmospheric monitoring equipment for compliance monitoring, ambient air assessment, and facility-level environmental control. The Oregon Department of Environmental Quality is procuring up to 50 FEM-certified integrating nephelometers with internal heaters and multi-wavelength measurement capability (response due November 17, 2026), while the Texas Commission on Environmental Quality has posted multiple bids for specialized analyzers, calibrators, and sensor systems supporting PM2.5, ozone precursor, and hydrogen sulfide monitoring networks. School districts are also active—Pinellas County School District is soliciting indoor air quality investigation and mitigation services including asbestos and mold testing (ITB response due November 6, 2026). Issuing bodies include state environmental departments, water utilities, school districts, and municipalities; the Texas Commission on Environmental Quality and state environmental quality agencies are repeat solicitors under this code.

The code shows significant recent activity across Texas, Oregon, Michigan, Georgia, and Florida. The Texas Commission on Environmental Quality alone has posted at least six recent competitive bids for air monitoring equipment and calibration systems, including requests for ozone precursor systems (TD/AutoGC/FID), dynamic dilution calibrators, zero-air supply systems, hydrogen sulfide spectrometers, canister samplers, and replacement parts. The Michigan Department of Environment, Great Lakes, and Energy is soliciting proposals for a specialized air monitoring shelter with climate control and mounting infrastructure (response due July 1, 2026). The Georgia Department of Agriculture Laboratory Division posted an RFQ for an environmental conditions monitoring system covering temperature and humidity sensors for laboratory facilities (response due August 21, 2026). The City of Phoenix Water Services Department issued an IFB for atmospheric monitoring instruments to detect hazardous gases at water and wastewater facilities (response due September 4, 2026). These procurements involve both capital equipment acquisition and long-term supply and maintenance contracts, with contract terms typically ranging from three to ten years and initial purchase orders often structured separately from optional future buy-down provisions.
