UNSPSC 41111954: Liquid sensor

UNSPSC 41111954 Liquid sensor (Commodity) covers analytical and measurement instruments used to detect, monitor, and quantify liquids in infrastructure and laboratory contexts, with state and local governments soliciting sensors, spectrometers, and related detection equipment for wastewater management, environmental testing, and research applications. Recent opportunities show municipal water departments and environmental agencies purchasing inductively coupled plasma mass spectrometers (ICP-MS) systems for metals analysis in water samples, bore scanners for subsurface liquid assessment, lock-in amplifiers for precision measurement, and video pipeline inspection systems coupled with liquid-detection and assessment functions to support sewer line and wastewater infrastructure inspection and management. Issuing bodies under this code include municipal water and watershed departments (City of Atlanta), state environmental protection agencies (Illinois Environmental Protection Agency), and higher-education research institutions (Texas A&M University System), with no single repeat buyer visible in recent postings.

The Illinois Environmental Protection Agency in St. Clair County solicited a complete ICP-MS system with collision reaction cell, autosampler, and Windows 11 PC for metals analysis under IFB 26-532EPA-LAB53-B-50817, due February 17, 2026, requiring ISO certification, manufacturer-backed support technicians, seven-year service guarantee, and general liability insurance of $1,000,000 per occurrence; the contract may qualify for a Small Business Set-Aside. The City of Atlanta Department of Watershed Management issued IFB GS/DWM/2604-1260190 on June 8, 2026 for color video pipeline inspection systems, sewer cleaning equipment, and OEM-certified accessories with one-year warranty and 24-hour parts availability, due June 23, 2026, requiring vendor registration through the City's supplier portal and certified machine-shop capability. Texas A&M University System posted two separate ITBs in late winter 2026 for a bore scanner (ITB TAMUS-ITB-26-0534, due March 25, 2026) and a lock-in amplifier (ITB TAMUS-ITB-26-0533, due February 26, 2026), both requiring electronic submission through AggieBid with limited public documentation available. Recent activity appears concentrated in Texas, Georgia, and Illinois, with infrastructure and environmental agencies driving demand.
