UNSPSC 41112233: Melting point measuring instrument

An instrument that is used to measures the melting point, namely, the temperature that a substance changes its phase from the solid state to the liquid state.

UNSPSC 41112233 Melting point measuring instrument is a Commodity code that encompasses temperature and vibration monitoring sensors, transmitters, thermocouples, and related instrumentation actually being procured by state and local water utilities, solid waste authorities, municipalities, and school districts. State and local buyers use this code to source industrial process monitoring equipment for water treatment facilities, wastewater systems, waste-to-energy operations, and facility infrastructure—not laboratory melting-point analysis devices. Issuing bodies include county water departments, city water services divisions, solid waste authorities, and public school nutrition programs. Recent solicitations show demand for thermocouples with thermowells, temperature and humidity monitoring systems for laboratory facilities, pressure and temperature transmitters for municipal water systems, vibration sensors for booster stations, and thermoplastic pavement marking applicators. Buyers source from authorized equipment distributors and specify exact part numbers and manufacturer designations (Precision Measurements, Apogee, Vaisala, Trantex, HS Series) rather than generic alternatives.

Geographic activity concentrates in Florida, Georgia, and Texas, with additional solicitations from Arizona and South Carolina. Representative recent opportunities include Gwinnett County Department of Water Resources issuing an Informal Written Quotation (IWQ 136938) for eight Model HS421 Series temperature transmitters and accelerometer assemblies for the Norcross Booster Station, due October 12, 2026; the City of Phoenix Water Services Department issuing a five-year IFB (26-0398) for pressure and temperature instrumentation from approved vendors including ABB, Honeywell, Emerson, and Siemens, due August 18, 2026; the City of Tampa issuing an ITB for thermocouples with thermowells from Precision Measurements for the McKay Bay Waste-to-Energy Facility, due May 12, 2026; and the Texas Water Development Board issuing an IFB (ESBD_548214) for temperature sensors, pyranometers, and related cables, due August 25, 2026. The Georgia Department of Agriculture Laboratory Division issued an RFQ for an environmental conditions monitoring system to replace aging equipment across fifty-eight critical units in Tifton and Atlanta, due August 21, 2026. Cooperative purchasing is standard; Phoenix Water Services allows Government Purchasing Council members to utilize the award under their own contracts.
