UNSPSC 47101516: Turbidimeters

UNSPSC 47101516 Turbidimeters, a Commodity code, covers hand-held and benchtop instruments that state and local water utilities deploy to measure water clarity, algae content, chlorophyll-a levels, and suspended solids in real-time field and lab settings. Recent solicitations show municipalities and counties purchasing single turbidimeters and related water-quality monitoring sondes for routine compliance testing, algae detection in freshwater systems, and integration into existing SCADA and analytical networks. The issuing bodies include city water departments (Tampa, Phoenix, Ocala), county water resources agencies (Brevard, Hillsborough, Fulton, Gwinnett), special districts (Holly Hill), and state environmental commissions (Texas Commission on Environmental Quality). Water utilities dominate the buyer base, with a handful of repeat purchasing activity from Tampa (three sole-source analytical equipment procurements in 2026) and Hillsborough County (established sole-source relationships with exclusive equipment manufacturers). The work spans equipment procurement only (single units or small batches), integration into existing water-quality monitoring infrastructure, and occasional bundling with calibration solutions, spare parts, and mobile application licensing.

Recent activity concentrates in Florida and Georgia, with secondary spread to Texas, Connecticut, Michigan, and Oregon. Representative opportunities include Brevard County's $15,992.20 sole-source procurement for a PPS Systems AlgaeTorch chlorophyll analyzer (December 2025 response deadline), the City of Tampa's Intent to Single Source for Swan Analytical Instruments parts and support (October 2026 deadline), the City of Tampa's RFQ for one Luminultra Bugcount One ATP Analyzer microbiological testing instrument (September 2026 deadline), the Texas Commission on Environmental Quality's IFB for YSI EXO multiparameter sondes and conductivity/temperature sensors (July 2026 deadline), and Okaloosa County's RFQ for a portable multi-parameter sonde capable of measuring temperature, conductivity, pH, dissolved oxygen, and depth with mobile-app communication (June 2026 delivery deadline). Sole-source and Intent to Single Source notices dominate the code; competitive procurement (RFQ, RFP, IFB, ITB) appears infrequently. Geographic concentration in Florida reflects the state's regulatory focus on algal bloom monitoring and saltwater intrusion detection in coastal and estuarine systems.
