UNSPSC 41112200: Temperature and heat measuring instruments

UNSPSC 41112200 Temperature and heat measuring instruments is a Class code encompassing thermometers, thermocouples, temperature transmitters, temperature switches, thermowells, and related sensing and measurement equipment that state and local governments procure for water and wastewater infrastructure, laboratory facilities, waste-to-energy operations, and municipal utility systems. Recent solicitations show state and local buyers acquiring temperature sensors and transmitters for booster stations, pressure and temperature instrumentation for water treatment facilities, environmental monitoring systems for laboratory storage and processing equipment, and specialized thermocouples for waste-to-energy facility operations. The issuing bodies span water and wastewater utilities (county and municipal departments of water resources), state laboratory divisions, solid waste authorities, and cities' water services departments.

Geographic activity centers on Florida, Georgia, and Texas. The City of Phoenix Water Services Department issued IFB 26-0398 on August 18, 2026, for a five-year pressure and temperature instrumentation contract covering transmitters, switches, gauges, thermowells, and resistance temperature detectors from approved manufacturers including ABB, Emerson, Honeywell, Siemens, and VEGA; Gwinnett County Department of Water Resources in Georgia solicited quotes under IWQ 136938 on October 5, 2026, for vibration and temperature monitoring sensors with delivery due October 12, 2026; the Texas Water Development Board requested bids under IFB ESBD_548214 on August 11, 2026, for temperature sensors and related instruments with a single-source specification framework; the Georgia Department of Agriculture Laboratory Division issued RFQ 40200ERFQ0018662027 on August 7, 2026, for an environmental conditions monitoring system covering temperature and humidity monitoring across fifty-eight critical laboratory units; and the City of Tampa issued RFQ 26-P-00315 in May 2026 for Precision Measurements thermocouples with thermowells for the McKay Bay Waste-to-Energy Facility.
