UNSPSC 41113124: Respirometer

A type of device that is designed to measure the discharge gases, such as carbon gas, that are released to outside of body for certain time, periodically or consecutively through the chemical change of substance within the body and building up the oxygen volume supplied from outside to sustain the plant or animal life.

UNSPSC 41113124 Respirometer is a Commodity code covering specialized analytical and monitoring equipment for gas, thermal, and environmental analysis. State and local governments procure under this code primarily laboratory instrumentation systems and field-based environmental monitoring devices—simultaneous thermal analysis systems used by research institutions, methane detection and calibration systems deployed across transit and wastewater facilities, portable particulate matter monitoring equipment for environmental inspections, and digester gas utilization equipment at water reclamation facilities. Recent solicitations show buying bodies range from research universities and county transportation authorities to municipal environmental services departments, wastewater districts, and public health laboratories, indicating scattered demand across higher-education, public utilities, and environmental regulation sectors rather than concentration in a single jurisdiction type.

Recent activity spans California, Texas, Florida, Michigan, and South Carolina. The Orange County Transportation Authority issued an IFB in June 2026 for methane detection system service and maintenance across five OCTA facilities with a $260,000 estimated value over four years and prevailing wage requirements under California law. The University of Wisconsin-Madison posted an RFB in July 2026 for a Simultaneous Thermal and Gas Analysis System with a response deadline of July 17, 2026. The City of Fort Worth issued an RFQt in March 2026 for portable real-time particulate matter monitoring equipment for field-based environmental inspections. The Eastern Municipal Water District in Riverside County solicited a Design-Build-Finance-Own-Operate-Maintain agreement in February 2026 for a Digester Gas Utilization Project converting digester gas from anaerobic sludge treatment into renewable natural gas, with mandatory site tours scheduled March 18–19, 2026, and a proposal deadline of April 13, 2026. Greenville County, South Carolina, issued RFP 26092 in February 2026 for landfill gas and air quality consulting services across three county landfills, with proposals due April 1, 2026.
