UNSPSC 41112200: Temperature and heat measuring instruments

UNSPSC 41112200 Temperature and heat measuring instruments is a Class code covering discrete temperature sensors, thermocouples, and related monitoring equipment that state and local governments procure for facility operations, environmental compliance, and laboratory accreditation. Recent solicitations show state and local buyers acquiring thermocouples with thermowells for waste-to-energy facilities, wireless temperature and humidity monitoring systems for forensic laboratory networks, and temperature-measuring components embedded in wastewater treatment control panels. The scope is narrower than the code's nominal name suggests — state and local buyers under this code are primarily sourcing specialized sensors and installed monitoring infrastructure rather than broad temperature-measurement instrumentation families. Issuing bodies include city utilities departments (wastewater, waste-to-energy), state environmental and public-safety agencies, and specialized state laboratories. Cities and state departments dominate the recent activity; school districts and transit authorities do not appear in the recent posting mix.

Geographic concentration is present in Florida and Massachusetts, with the City of Tampa posting two separate opportunities (one ITB for wastewater inventory components including process meters due August 6, 2026, and one RFQ for 24 thermocouples with 446 stainless steel construction for McKay Bay Waste-to-Energy Facility due May 12, 2026) and the Massachusetts Department of State Police, Forensic Services Division posting a request for response for wireless and computer-based environmental monitoring systems across nine crime lab facilities statewide, with responses due April 22, 2026, and an anticipated contract value of approximately $12,268 annually. The Florida Department of Health also posted a single-source procurement for laboratory testing supplies that encompassed temperature measuring instruments as a line item. Activity is episodic rather than continuous; the code shows no evidence of standing cooperative purchasing vehicles or repeat-buyer patterns across multiple jurisdictions. Responsiveness requirements, calibration standards (NIST-traceable sensors), and warranty terms (one year on materials and workmanship) are common threads in recent solicitations.
