UNSPSC 41112306: Humidity calibrator

A type of device that is designed to test the capability of the device that measures humidity and the normal operation thereof.

UNSPSC 41112306 Humidity calibrator is a Commodity code that in recent state and local solicitations frames work around calibration, cleaning, and maintenance of specialized environmental measurement and safety equipment rather than humidity measurement alone. The County of Orange, Sheriff-Coroner issued an IFB in May 2026 for annual cleaning and calibration of TSI PortaCount Pro Respirator Fit Testers under a three-year contract with two optional renewal years, requiring annual software and firmware updates and return of serviced units within 14 days, with a five percent preference for Orange County Local Small Business or Disabled Veteran Business Enterprise vendors. State and local issuing bodies posting under this code span counties and specialized departments (sheriff-coroner, parks and airports, transportation, and higher education); the County of Orange has appeared multiple times in procurement activity. Qualifications typically require proof of insurance with Commercial General Liability and Workers' Compensation at specified levels, valid D-U-N-S and UEI numbers, and performance and payment bonds where applicable. Contract structures are firm fixed-fee with annual invoicing and net 30 payment terms, federal grant funding partial support, and compliance with standards including OSHA, NIOSH, and ANSI.

Recent opportunities show activity concentrated in California and Florida, with additional procurement from Georgia (GDOT's April 2026 eRFQ for Automated Weather Observing System commodities, deadline May 4, 2026) and Texas (Texas Tech University's March 2026 RFP for weather radar deployment under the Texas Flood Project, RFP 2026-1183, with award anticipated July 2026, requiring HUB subcontracting and NIST 800-53 cybersecurity controls). Brevard County, Florida issued a sealed-bid solicitation in February 2026 for lightning protection system installation at two courthouse locations, with mandatory pre-bid walk-throughs and a lump-sum pricing structure. The code shows real activity tied to environmental monitoring, safety equipment maintenance, and field instrumentation across multiple states, though the scope diverges significantly from the abstract "humidity calibrator" label—recent opportunities emphasize respirator testing equipment, weather systems, and lightning detection rather than humidity measurement in isolation. Geographic spread is concentrated in the Southeast and Southwest, with California and Florida as repeat buyers.
