UNSPSC 41113057: Sludge densitometer

A type of device that measures the sludge, such as solid substance or floating substance contained in the liquid of water source or waste water from the plant.

UNSPSC 41113057 Sludge densitometer is a Commodity code that covers precision laboratory and field instrumentation used to measure and monitor material density, consistency, and physical properties across municipal water, wastewater, environmental, and research operations. State and local governments procure densimeters and allied measurement devices — including spectrophotometers, optical surface profilometers, photometric test systems, and other analytical instruments — to support water quality monitoring, treatment process control, equipment testing, and scientific research at public utilities, universities, and environmental agencies. Recent solicitations show water utilities purchasing TOC analyzers and oil testing laboratory services for transformer diagnostics, wastewater agencies acquiring meter test boards and airfield lighting assessment systems, and academic institutions sourcing optical measurement equipment and drug discovery software platforms. Issuing bodies include municipal utility authorities, county water and wastewater departments, city electric and solid waste divisions, state departments of health services, university systems and independent institutions, and port authorities. Florida jurisdictions—particularly the City of Tampa, City of Ocala, Lee County Port Authority, and Collier County—appear frequently in recent activity alongside Texas state agencies (DSHS, Texas A&M, Texas State University) and municipal utilities in Arizona, Colorado, and Oregon.

Recent opportunities span diverse instrumentation but cluster around utility process control and environmental compliance. Lee County Port Authority issued two e-quotes (August and October 2026, due dates August 20 and October 29) for airfield photometric testing at Southwest Florida International Airport, with three-year terms and FAA compliance requirements. City of Tampa issued an RFQ (June 2026, due June 12) for a Heck DR4900 spectrophotometer to replace an existing unit at the McKay Bay Waste to Energy facility. Texas Department of State Health Services, through HHSC, posted IFB HHS0017421 (June 2026, due July 6) and a revised version HHS0017421V2 (August 2026, due August 26) for laboratory equipment repair and maintenance covering sterilization and washing units at the South Texas Laboratory in Harlingen, with estimated annual costs of $25,050 to $40,000 and contract term through August 31, 2031 with renewals. City of Ocala Electric Utility issued RFP ELE/260570 (September 2026, due April 30) for a three-phase meter test board with 0.04% accuracy and AMI compatibility, scoring on qualifications (25 points), technical compliance (50 points), and price (25 points). Kissimmee Utility Authority posted IFB 26046JG (September 2026, due September 22) for an OMICRON CP TD12 capacitance and dissipation factor measurement module with contract value under $250,000. City of Phoenix Water Services Department issued IFB-27-0435 (August 2026, due September 4) for atmospheric monitoring instruments and fixed gas detection systems at water and wastewater facilities under a five-year contract with DBE-Neutral participation requirements. Lubbock Power & Light solicited RFP 7131-26-ELD (June 2026, due July 22) for annual insulating oil testing laboratory services across 20 substations, requiring ISO/IEC 17025 accreditation and five years of utility experience, with evaluation weighted to technical qualifications (35%), LIMS data integration (25%), engineering support (20%), pricing (15%), and proposal completeness (5%).
