UNSPSC 41113119: Dissolved carbon dioxide analyzers

UNSPSC 41113119 Dissolved carbon dioxide analyzers (Commodity) represents atmospheric and process monitoring instrumentation—principally gas sensors, flow meters, calibration devices, and related analytical equipment—that state and local water, wastewater, environmental, and solid waste agencies purchase to monitor, control, and verify treatment processes and regulatory compliance. Recent solicitations show state and local buyers acquiring atmospheric hazard detection systems, ultrasonic and clamp-on flow measurement devices, gas flow calibrators, mass flow terminals, and meter calibration services; the code also tags integrated engineering procurements for waste-to-energy and renewable natural gas facilities where process instrumentation and monitoring form part of a larger scope.

Issuing bodies include county solid waste and environmental authorities, municipal water and wastewater departments, city water services divisions, state environmental commissions, and regional water districts. Geographic activity spans Florida (Solid Waste Authority of Palm Beach County, Collier County, City of Tampa), Arizona (City of Phoenix), Wisconsin (Dane County), Texas (Texas Commission on Environmental Quality, Texas General Land Office), and California (Eastern Municipal Water District). Representative recent opportunities include the Solid Waste Authority of Palm Beach County's RFEI for design-build-operate-maintain services on a mass-burn waste-to-energy facility (response due November 18, 2026); the City of Phoenix Water Services Department's IFB for atmospheric monitoring instruments—fixed installations at water and wastewater facilities, with sealed offers due September 4, 2026; the Texas Commission on Environmental Quality's RFB for gas flow calibrators including Mesa Labs Series ML-800 base units and flow cells (bids due July 7, 2026); and Dane County's RFP for renewable natural gas facility replacement and commissioning, including nitrogen and carbon removal unit upgrades, with proposals due September 3, 2026.
