UNSPSC 41113120: Carbon monoxide analyzer

An instrument used to measure carbon monoxide(CO) in gas.

UNSPSC 41113120 Carbon monoxide analyzer is a Commodity code covering fixed and portable gas detection equipment used by state and local water, wastewater, environmental, and waste management agencies to monitor hazardous atmospheres at treatment facilities, lift stations, confined spaces, and landfill operations. State and local governments procure these instruments as part of broader atmospheric monitoring systems, often bundled with sensors for hydrogen sulfide, methane, oxygen depletion, chlorine, ammonia, and other process gases. Recent solicitations reflect purchasing by water and wastewater utilities, environmental quality agencies, and waste-to-energy operators acquiring detection equipment paired with controllers, alarms, calibration materials, and replacement parts for multi-year service agreements. Issuing bodies include water utilities (municipal water and wastewater departments), county environmental agencies, state air quality commissions, and special-purpose waste authorities. Contracts typically run three to five years with firm-fixed pricing for initial periods, annual price adjustments, local parts stocking requirements, operator training, and technician certification mandates.

Recent activity concentrates in Florida, California, Texas, and Wisconsin. The City of Phoenix Water Services Department posted an IFB on August 14, 2026 (due September 4) for atmospheric monitoring instruments—fixed installations to detect carbon monoxide and seven other gases at water and wastewater facilities under a five-year contract, with DBE-Neutral participation requirements and approved manufacturers including ATI, De Nora, Drager, and MSA. The Solid Waste Authority of Palm Beach County issued a Request for Expressions of Interest on September 11, 2026 (due November 18) for a mass-burn waste-to-energy facility DDBOM project incorporating air pollution control equipment and gas monitoring as part of facility design and operations. The Texas Commission on Environmental Quality Air Monitoring Division solicited bids on June 30, 2026 (due July 7) for gas flow calibrators meeting NIST traceability and EPA gas verification protocols for laboratory calibration of monitoring equipment. Eastern Municipal Water District (Riverside County, California) posted an RFP on June 9, 2026 (due July 15) for meter verification, calibration, and certification services incorporating related atmospheric monitoring support within California's water utility market.
