UNSPSC 41114421: Hygrometer calibrator

Equipment that is used to determine the correction value of the scale inscribed on the hygrometer used for the measurement of humidity in atmosphere by adding the water into the chamber and heat it to change the humidity to 30 percent, 60 percent, and 90 percent.

UNSPSC 41114421 Hygrometer calibrator is a Commodity code that does not align with the recent state and local solicitations tagged under it. The code nominally covers hygrometer calibration instruments, but the four most recent opportunities solicited under this code are for lightning detection and prediction systems, automated weather observation systems, weather radar deployment, and lightning protection system installation—none of which involve hygrometer calibration equipment or services. This mismatch suggests either a systematic coding error in the source data or that state and local procurement systems are using this code to capture a broader range of environmental monitoring and weather infrastructure instruments than the code name implies.

The recent opportunities show activity from Florida county governments (Broward County and City of Fort Lauderdale, Brevard County), a state department of transportation (Georgia Department of Transportation), and a state university (Texas Tech University). Geographic spread spans Florida, Georgia, and Texas, with opportunities posted between February and May 2026. Representative recent solicitations include Broward County's RFI regarding the Thor Guard Inc. TG-360 Lightning Prediction and Detection System (due May 18, 2026), Georgia Department of Transportation's eRFQ for Automated Weather Observing System commodities (due May 4, 2026), Texas Tech University's RFP for weather radar deployment with mandatory HUB subcontracting and NIST cybersecurity controls (proposals due March 6, 2026), and Brevard County's sealed-bid solicitation for lightning protection system installation at two courthouses (bids due January 27, 2026, with UL or LPI certification required). Given the disconnect between the code's nominal scope and actual procurement activity, business development professionals should treat this code as unreliable for hygrometer-related opportunities and verify code assignment before investing pursuit effort.
