UNSPSC 41112244: Calibration reference thermometer

A calibrated reference thermometer, certified by the National Institute of Standards and Technology, NIST, that maintains metrologic traceability, and that is utilized to calibrate or verify that any other thermometer will measure within that specific temperature range in which the thermometer is designed to operate

UNSPSC 41112244 Calibration reference thermometer is a Commodity code that encompasses temperature and vibration monitoring sensors, transmitters, and associated instrumentation deployed in municipal water systems, wastewater treatment facilities, waste-to-energy operations, and environmental monitoring applications. State and local governments procure these sensors as components within larger system upgrades or operational monitoring infrastructure—most recent activity centers on pressure and temperature transmitters for water utility distribution networks, vibration and temperature monitoring equipment for pump stations and critical facility infrastructure, and EPA-protocol calibration gases for emissions monitoring at waste facilities. Issuing bodies include water utilities (county and municipal departments), public works agencies, environmental authorities, and special districts. The City of Phoenix Water Services Department, Gwinnett County Department of Water Resources, and the County of Orange (California) Public Works represent recent repeat or substantial buyers; school systems and solid waste authorities also appear in the recent record, though their procurement is ancillary to broader facility management or operational support contracts.

Activity spreads across Florida (City of Port Orange, City of Tampa, Solid Waste Authority of Palm Beach County, Orange County California), Georgia (Gwinnett County, Georgia Department of Agriculture), Texas (Texas Water Development Board), and Arizona (City of Phoenix). Representative recent opportunities include Gwinnett County Department of Water Resources' IWQ 136938 for eight Model HS421 Series Transmitters with PT100 temperature sensors and accelerometer cable assemblies, due October 12, 2026; City of Phoenix Water Services' five-year IFB 26-0398 for pressure and temperature instrumentation equipment including transmitters, switches, gauges, and thermowells from approved manufacturers (ABB, Ashcroft, Endress+Hauser, Honeywell, Omega, Siemens, VEGA), commencing October 15, 2026; and the Texas Water Development Board's IFB ESBD_548214 for temperature sensors, Apogee pyranometers, and RM Young instruments due August 25, 2026. County of Orange's competitive bid for EPA Protocol Calibration and Audit Gases (five-year usage agreement with firm fixed pricing, local small business 5% preference, 24-hour delivery capability) reflects sustained investment in emissions monitoring infrastructure.
