UNSPSC 41113026: Nephelometers

UNSPSC 41113026 Nephelometers is a Commodity code that in current state and local procurement activity covers lightning detection, weather monitoring, and related sensor systems rather than the narrow atmospheric-measurement instruments the code name suggests. State and local buyers under this code are soliciting lightning protection installation, lightning detection hardware and software, weather station maintenance, and related severe-weather alerting systems. Issuing bodies include state military departments, county governments, and airport authorities. The Texas Military Department, Hillsborough County, the Texas Water Development Board, and Broward County with the City of Fort Lauderdale have all posted opportunities under or near this code in recent months, indicating activity across state departments, counties, and special-purpose authorities managing infrastructure and public-safety functions.

Recent activity concentrates in Texas and Florida. The Texas Military Department issued IFB TMD26FMO0044558 on September 12, 2026 for lightning protection system installation at eight sites at Camp Swift in Bastrop, Texas, with bids due September 26, 2026 and a mandatory pre-bid site visit on September 16, 2026; respondents must demonstrate two to five years of commercial lightning protection experience and carry $1 million in Professional Liability coverage. Hillsborough County posted a sole-source procurement notice SS2600405 on September 3, 2026 for Earth Networks hardware, software, and maintenance of its lightning detection and severe weather monitoring system, with an estimated two-year contract value of $47,627.54 and challenges due September 11, 2026. The Texas Water Development Board issued IFB 58025IFB5519 on August 11, 2026 for temperature sensors and related meteorological instruments, due August 25, 2026. Broward County and the City of Fort Lauderdale issued an RFI on May 6, 2026 regarding a Thor Guard lightning prediction and detection system for integration with existing infrastructure at County Parks and Fort Lauderdale-Hollywood International Airport, with responses due May 18, 2026. The code shows mismatch between its formal scope and actual procurement intent — few opportunities involve nephelometry per se, and buyers are concentrated on lightning safety and detection rather than general atmospheric monitoring.
