UNSPSC 41113119: Dissolved carbon dioxide analyzers

UNSPSC 41113119 Dissolved carbon dioxide analyzers is a Commodity code that covers gas flow calibration equipment, mass flow standards, zero air generators, and related analytical instrumentation used in environmental monitoring and laboratory calibration operations. State and local governments acquire these devices to verify, calibrate, and maintain air and water quality monitoring networks, often in support of Environmental Protection Agency compliance requirements. The issuing bodies include state environmental protection agencies, municipal water districts, county governments, and special-purpose environmental authorities across multiple states. Texas agencies, particularly the Texas Commission on Environmental Quality, appear as repeat buyers of gas flow calibrators and mass flow terminals for air monitoring laboratory operations.

Recent opportunities span Texas, Illinois, California, and Florida. The Texas Commission on Environmental Quality issued an RFB for gas flow calibrators due July 7, 2026, specifying Mesa Metrology Series ML-800 base units with three interchangeable flow cells (Item #5822615780). The same agency previously solicited a Molbox2-A700K mass flow terminal (manufactured by Fluke Electronics) under RFB 5822615424, due March 31, 2026.
