UNSPSC 41111973: Particle counter

A counter that measures the number of particles for extremely finite pulverulent body or makes comparative measurement that are found in liquid, such as working oil, ultra pure water and others.

UNSPSC 41111973 Particle counter is a Commodity code that maps poorly to the recent state and local opportunities posted under it. The solicitations tagged with this code involve wastewater infrastructure inspection and cleaning equipment (color video pipeline systems and sewer inspection units), advanced instructional materials and CTE equipment for K–12 education, laboratory analytical instruments (a bore scanner, lock-in amplifier, and ICP-MS system for metals analysis), and related services—none of which are particle counters or air/liquid particle-counting devices. The mismatch suggests either inconsistent UNSPSC coding by issuing bodies or a taxonomy tag that does not align with the actual procurement scope.

The recent activity shows a diverse issuing-body mix including a municipal water utility (City of Atlanta Department of Watershed Management), an independent school district (Klein ISD, Texas), a university system (Texas A&M), and a state environmental agency (Illinois EPA). Geographic spread spans Texas, Georgia, and Illinois. The only opportunity with clear connection to instrumentation procurement is the Illinois EPA's February 17, 2026 IFB for an ICP-MS system for metals analysis—a specialized analytical instrument requiring ISO certification, manufacturer support, on-site training, and a seven-year service guarantee. Because the code shows little relevant recent activity aligned with its stated commodity definition, business development professionals should verify with specific issuing bodies whether particle-counter procurement is planned or whether alternate UNSPSC classifications better capture their target market.
