NIGP 17527: Electrode Sensing Meters and Electrodes: Dissolved Oxygen, pH, Specific Ion, etc.

NIGP 17527 Electrode Sensing Meters and Electrodes: Dissolved Oxygen, pH, Specific Ion, Etc., Item, encompasses water and wastewater monitoring equipment including dissolved-oxygen sensors, pH probes, level sensors, and related analytical instrumentation that state and local governments procure to support regulatory compliance and facility operations. Recent solicitations from state and local buyers show demand for specialized monitoring hardware for water reclamation facilities, laboratory analytical services bundled with electrode-based testing, and sensor systems integrated with existing treatment-plant infrastructure. The issuing-body mix spans municipalities (Bradenton and Palm Bay, Florida; Detroit, Michigan; Austin, Texas) and higher-education institutions (University of Wisconsin-Whitewater acting on behalf of Wisconsin state government), with city water and wastewater utilities as primary buyers. Electrode and sensing-meter procurement under this code reflects both direct equipment purchases and embedded components within broader laboratory testing and facility-monitoring contracts rather than standalone commodity buys.

Recent opportunities in this space include the City of Bradenton's sole-source notice (26038NT, posted July 1, 2026, due July 1, 2026) for WRF level sensors and controllers from The Avanti Company; the City of Palm Bay's Invitation to Bid 19ITB26 (posted April 13, 2026, deadline March 17, 2026) for comprehensive laboratory testing services across water and wastewater facilities, encompassing 188 line items of analyses many of which rely on electrode-based measurement (pH, conductance, dissolved oxygen), with three bids received ranging from $80,872 to $107,946 and historical annual spending of $66,360 to $95,440; and the University of Wisconsin-Whitewater's competitive bid (2026UWWTW01224RFB, posted February 5, 2026, due February 20, 2026) for a standalone oxygen consumption monitor. Geographic activity centers on Florida and the Midwest, with Texas and Wisconsin also showing recent procurement. The code sees modest but recurrent activity driven by municipal water-quality monitoring mandates and state regulatory reporting requirements rather than high-volume commodity demand.
