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 thermocouples, thermowells, calibration gases, and related temperature and emissions-monitoring equipment used in industrial and environmental facilities. State and local governments procure these components primarily for wastewater treatment, solid waste-to-energy facilities, and air quality compliance monitoring. The solicitations show a mix of issuing bodies — city public works departments, county utilities and public works agencies, and school district facility operations — each procuring specialized instrumentation to support infrastructure operations and regulatory compliance. Scope ranges from one-off purchases of precision thermocouples for specific retrofit or replacement work to recurring supply agreements for EPA Protocol calibration and audit gases required by continuous emissions monitoring systems under air-quality regulations.

Activity is concentrated in Florida and California. The City of Tampa issued an RFQ in May 2026 for 24 precision thermocouples with thermowells (Part# CI1-MS14K-I-446-MTP-38-28.5-26.25-446-SP) for its McKay Bay Waste-to-Energy Facility, with quotes due May 12, 2026 and delivery within a timeframe to follow order receipt. Orange County Public Works in Santa Ana, California is requesting competitive bids through August 10, 2026 for EPA Protocol calibration and audit gases — 13 line items including four calibration gases, four low-range audit gases, and five high-range audit gases — for a five-year usage agreement supporting the County's cogeneration gas turbine CEMS in compliance with South Coast Air Quality Management District emissions requirements; bids receive a 5% preference for Orange County Local Small Business or Disabled Veteran Business Enterprise certification. The City of Tampa also issued an ITB in July 2026 (due August 6, 2026) for wastewater inventory components including pressure switches and process meters, sheltered to Small Local Business Enterprise certified bidders with a 5% bid discount capped at $10,000.
