UNSPSC 41114425: Actinometer calibrator

A standard pyrheliometer that is used to determine the correction value of the pyrheliometer. It simultaneously measures with the same environment condition of the subject pyrheliometer to determine the correction value from the difference of measurement value of both.

UNSPSC 41114425 Actinometer calibrator is a Commodity code with little recent activity aligned to its nominal scope. The recent state and local opportunities tagged to this code address lightning protection, lightning detection and monitoring systems, and weather instrumentation — products and services that fall outside the narrow specification of an actinometer calibrator, which measures solar radiation intensity. The mismatch between the code's abstract name and the work actually being solicited suggests this code sees minimal or misclassified state and local procurement activity.

The four recent opportunities span Texas state agencies, a county government, and a county-city joint procurement. The Texas Military Department posted an IFB for lightning protection system installation at Camp Swift in Bastrop (response date September 26, 2026); Hillsborough County issued a sole-source notice for Earth Networks lightning detection and severe weather monitoring hardware and software at $47,627.54 for two years (response date September 11, 2026); the Texas Water Development Board requested bids on temperature sensors, pyranometers, and associated mounting equipment (response date August 25, 2026); and Broward County and the City of Fort Lauderdale jointly posted an RFI on the Thor Guard TG-360 lightning prediction and detection system (response date May 18, 2026). Geographic activity centers on Texas and Florida. Given the substantial divergence between the code's technical definition and the solicitations tagged to it, this code does not represent a coherent procurement category for current state and local practice.
