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 that in recent state and local practice encompasses lightning detection and prediction systems, automated weather observation equipment, and weather radar deployment — instrumentation and systems for meteorological measurement, atmospheric monitoring, and severe-weather early warning. State and local governments soliciting under this code include county governments (Broward County, Brevard County), state transportation departments (Georgia Department of Transportation), and higher-education institutions operating research facilities on behalf of state agencies (Texas Tech University). The work spans procurement of equipment alone, full system integration with existing infrastructure, installation and commissioning services, and multi-year maintenance and support contracts. Lightning protection systems for critical infrastructure (courthouse buildings) and weather monitoring systems for transportation safety and flood forecasting represent the primary use cases in recent activity.

Recent opportunities show geographic concentration in the Southeast and Texas. Broward County (Florida) issued an RFI for a Thor Guard TG-360 Lightning Prediction and Detection System on May 6, 2026, with responses due May 18, 2026, to evaluate sole-source designation for integration with existing systems at County Parks and Fort Lauderdale-Hollywood International Airport. Brevard County (Florida) solicited sealed bids for lightning protection system installations at two courthouses in February 2026, with bids due January 27, 2026, requiring UL or Lightning Protection Institute certification. The Georgia Department of Transportation posted an eRFQ for Automated Weather Observing System (AWOS) commodities on April 8, 2026, with quotes due May 4, 2026. Texas Tech University issued RFP 2026-1183 on March 6, 2026, for procurement, installation, commissioning, and five-year maintenance of three C-band dual-polarization weather radars with towers, shelters, power, and networking infrastructure to support the Texas Flood Project authorized by SB5 (2025), with a mandatory Historically Underutilized Business subcontracting plan under Texas Government Code 2161.252.
