UNSPSC 41113649: Psophometer

An instrument that provides a visual indication of the audible effects of disturbing voltages of various frequencies

UNSPSC 41113649 Psophometer is a Commodity code naming a laboratory instrument used to measure sound levels and acoustic properties in environmental or industrial settings. Recent state and local solicitations tagged with this code, however, reveal a substantial mismatch: the procurement activity centers on water quality laboratory analysis, analytical equipment maintenance, and environmental monitoring systems—none of which involve psophometers or sound measurement. The City of Santa Monica's ITB for laboratory analysis of water, wastewater, stormwater, and recycled water samples (due October 21, 2026) exemplifies the actual scope being solicited—contracted testing for treated drinking water, raw groundwater, brackish groundwater, seawater, raw wastewater, pretreatment effluent, treatment plant process flows, urban runoff, and advanced treated recycled water, with contractors required to maintain ELAP, TNI, ISO, and EPA accreditation and provide five years of documented experience in similar laboratory services. Other representative opportunities include Escambia County's requests for IDEXX supplies for fecal-indicating-bacteria testing in water-quality laboratories (due August 24, 2026, estimated annual cost $50,000), service contracts for highly specialized water-analysis instruments (Millipore Milli-Q Direct 8 and Seal Analytical AQ400), and the City of Arlington's procurement of a cyanide flow analyzer for wastewater treatment operations (due September 10, 2026). The City of Dallas also solicited repair services for an analytical lab spectrophotometer door and purchase of a solvent evaporation system for its Water/Research & Control Lab.

The issuing-body mix spans municipal water utilities, county environmental and health departments, and city laboratories across Florida, Arizona, California, Texas, Connecticut, Oregon, and Michigan. Water departments and environmental compliance divisions dominate the activity—Santa Monica Water Resources Division, Tucson Water, Arlington Water Utilities, Meriden Water Department, and the Oregon State Public Health Laboratory all posted recent opportunities. The geographic spread concentrates in Arizona (Tucson), Florida (Escambia County, Palm Bay), California (Santa Monica), and Texas (Arlington, Dallas), with secondary activity in Connecticut, Oregon, and Michigan. The code shows no recent activity aligned with its nominal scope of sound measurement; the UNSPSC classification appears misapplied to water and environmental laboratory procurement. Vendors pursuing this code should verify the actual scope with issuing agencies before bid preparation, as the taxonomy label does not reflect what is actually being bought.
