UNSPSC 41113051: Oxidation reduction tester

A tester that measures the ratio of oxidation-reduction of soluble substances within the solution.

UNSPSC 41113051 Oxidation reduction tester is a Commodity code. State and local governments procure laboratory testing equipment and analytical instrumentation under this code, including optical surface profilers for precision measurement, spectrophotometers for water quality analysis, three-phase meter test boards for electric utility metering programs, airfield photometric testing systems for runway and taxiway lighting compliance, and technical support agreements for specialized analytical platforms. Issuing bodies span higher education institutions (Valencia College, Jackson State University, Texas State University, Texas A&M University System), municipal utilities (City of Ocala Electric Utility, Kissimmee Utility Authority, City of Tampa Water Services, Lubbock Power & Light), county water and wastewater authorities (Lee County Port Authority, Collier County), state health agencies (Texas Department of State Health Services), cities (City of Phoenix, City of Orlando), and the Colorado State Patrol. Acquisitions are split fairly evenly between sole-source and competitive procurements, with many sole-source notices reflecting vendor-specific equipment replacements or established system integrations that limit alternate sources.

Recent activity concentrates in Florida, Texas, and the Southwest. Representative opportunities include Valencia College's Notice of Intended Sole Source for a PGI Optics CORE optical surface profilometer (posted October 19, 2026); Lee County Port Authority's RFQ for airfield photometric testing at Southwest Florida International Airport (due October 29, 2026); the City of Ocala Electric Utility's RFP for a three-phase meter test board (due April 30, 2026); Kissimmee Utility Authority's IFB for an OMICRON CP TD12 high-voltage testing module (due September 22, 2026); Jackson State University's sole-source purchase of Schrodinger drug discovery software (objections due October 13, 2026); the Texas Health and Human Services Commission's IFB for laboratory sterilization equipment repair and maintenance at DSHS South Texas Laboratory (due August 26, 2026); the City of Phoenix Water Services' IFB for atmospheric monitoring instruments for hazardous gas detection at water facilities (due September 4, 2026); and Lubbock Power & Light's RFP for annual insulating oil testing laboratory services (due July 22, 2026). Contract values range from $25,000 (City of Tampa Tekmar analyzer support, 12-month term) to $65,318.25 (Jackson State University five-year Schrodinger license). Most competitive solicitations emphasize technical capability and experience references; sole-source procurements typically cite equipment manufacturer exclusivity or system integration constraints.
