UNSPSC 41113122: Olfactometer

A type of experiment device for laboratory that seeks the applicable dilute magnification by diluting until no more sense of odor.

UNSPSC 41113122 Olfactometer is a Commodity code that encompasses laboratory and environmental monitoring equipment used to detect, measure, and analyze gases, particulates, and chemical compounds in air and wastewater applications. State and local governments procure under this code primarily for environmental compliance, public health monitoring, and utility operations—specifically real-time particulate matter detection systems, methane and digester gas monitoring and sensing equipment, simultaneous thermal and gas analysis systems, and authorized maintenance and repair services for existing analyzer systems. The issuing bodies span university research facilities, environmental departments within cities, county environmental agencies, water and wastewater utilities, and public health laboratories. Recent solicitations show activity from higher-education institutions (University of Wisconsin-Madison), municipal environmental and fire departments (City of Tampa, City of Detroit, City of Fort Worth), county-level agencies (Orange County Transportation Authority in California, Santa Clara County Public Health Lab, Greenville County South Carolina landfill operations), regional water utilities (Eastern Municipal Water District in Riverside County, California), and school district procurement for instructional resources.

Geographic activity centers on California (Orange County Transportation Authority methane detection system service and maintenance; Eastern Municipal Water District digester gas utilization project), Texas (Fort Worth portable particulate matter monitoring equipment, Klein ISD instructional resources including monitoring equipment), South Carolina (Greenville County landfill gas and air quality consulting), Florida (City of Tampa ChemScan analyzer parts and service), Michigan (Detroit Fire Department oxygen supply), and Wisconsin (University of Wisconsin-Madison thermal and gas analysis system). Representative recent opportunities include Orange County Transportation Authority IFB 250322 for methane detection system service and maintenance at five OCTA facilities (due June 1, 2026, $260,000 estimated value over four years), City of Fort Worth RFQ 26-0142 for portable real-time particulate matter monitoring equipment for field-based environmental inspections (due March 23, 2026), and Eastern Municipal Water District RFP 3900 for a Design-Build-Finance-Own-Operate-Maintain digester gas utilization project at three regional water reclamation facilities (proposals due April 13, 2026, with mandatory pre-proposal meeting March 9, 2026 and site tours March 18–19, 2026).
