UNSPSC 41111939: Acoustic sensors

UNSPSC 41111939 Acoustic sensors (Commodity) covers detection and monitoring equipment for sound, atmospheric, environmental, and laboratory applications, but recent state and local opportunities show the code being applied to a broader range of sensing instruments than its name suggests. State and local governments are purchasing acoustic and environmental monitoring systems, atmospheric hazard detection equipment, laboratory analytical instruments, and related installation and training services under this classification. The issuing bodies include school districts, municipal utilities and environmental departments, state environmental protection agencies, university systems, and specialized laboratory divisions. Procurement vehicles range from IFBs for sound system equipment and hazard detection sensors to RFQs for environmental monitoring systems and ITBs for analytical instrumentation.

Activity spans at least three states with recent high-profile opportunities from Georgia, Illinois, Arizona, and Texas. Clayton County Public Schools (Georgia) issued IFB 002-27 on October 1, 2026, for musical equipment, labs, and sound systems with a November 5, 2026 response deadline and a 15 percent Small Local Business Enterprise contracting goal; the City of Phoenix Water Services Department (Arizona) solicited sealed offers under IFB-27-0435 (due September 4, 2026) for atmospheric monitoring instruments to detect hazardous gases at water and wastewater facilities, including hydrogen sulfide, methane, and chlorine detection at lift stations and confined spaces, with a five-year contract term and DBE-N program participation requirements. The Illinois Environmental Protection Agency posted two opportunities—IFB 26-532EPA-LAB53-B-53209 (due September 1, 2026) for a tandem mass spectrometer system for pesticide analysis in surface water, and IFB 26-532EPA-AIR53-B-53592 (due August 27, 2026) for ozone transfer standards and zero air generators—both applying Illinois Business Preference and potentially triggering small business set-asides. The Georgia Department of Agriculture Laboratory Division issued RFQ 40200ERFQ0018662027 (due August 21, 2026) for an environmental conditions monitoring system covering temperature and humidity monitoring across fifty-eight critical units at laboratory facilities in Tifton and Atlanta.
