UNSPSC 41112223: Compound gauge

A visual indicator of pressure that is set for 'zero' psi at atmospheric pressure and includes a dial which will continue to indicate the level of pressure above or below atmospheric pressure.

UNSPSC 41112223 Compound gauge is a Commodity code that covers pressure gauges, temperature sensors, vibration monitoring equipment, and related instrumentation deployed across municipal water, wastewater, and reclaim water systems for process monitoring, troubleshooting, and preventative maintenance. State and local governments buy these instruments to measure system pressure on distribution and collection lines, assess pump station performance, detect equipment wear, and verify compliance with environmental permits. Recent solicitations show a mix of off-the-shelf replacement gauges and specialized transmitters with cable assemblies and mounting hardware. Issuing bodies include water and wastewater utilities, county departments of water resources, and municipal water services departments—repeat buyers are Hillsborough County and Collier County in Florida, each with multiple solicitations in the past three months. The code spans one-time commodity purchases of Ashcroft pressure gauges (200 units across Hillsborough County's 700+ pump stations) alongside specialized vibration and temperature monitoring equipment for booster stations and multi-year framework contracts for pressure transmitters, temperature switches, and diaphragm seals to support municipal treatment facilities.

Recent activity concentrates in Florida and Arizona. Gwinnett County Department of Water Resources (Georgia) solicited quotes on Informal Written Quotation IWQ 136938 due October 12, 2026 for eight HS421 Series temperature transmitters with accelerometer cable assemblies and studs for the Norcross Booster Station. The City of Tampa issued RFQ 26-P-00548 due October 6, 2026 for twenty-four line items of pressure gauges and related equipment across various types and manufacturers. Hillsborough County Board of County Commissioners solicited competitive sealed bids under ITB-26-00392 due September 21, 2026 for 200 Ashcroft pressure and vacuum gauges ($65,148.80 estimated value) deployed across water, wastewater, and reclaim water operations. The City of Phoenix Water Services Department issued IFB 26-0398 due August 18, 2026 for a five-year contract on pressure transmitters, temperature switches, gauges, diaphragm seals, thermowells, and related accessories from approved manufacturers for municipal water and wastewater treatment facilities, with a pre-offer conference scheduled for August 4, 2026. Award criteria across these opportunities prioritize lowest responsive and responsible bidding, authorized distributor status, demonstrated experience supplying similar instrumentation to water utilities, and local stocking capability for replacement parts.
