UNSPSC 41115603: pH meters

UNSPSC 41115603 pH meters is a Commodity code that captures laboratory and facility-monitoring instruments used in water quality, wastewater treatment, and environmental testing—though recent state and local solicitations show the code applied to a broader range of analytical and sensing equipment than pH measurement alone. The City of Palm Bay issued ITB 19ITB26 in April 2026 for comprehensive laboratory testing services across water, wastewater, and groundwater programs, encompassing 188 line items with unit prices ranging from $0 for calculated field measurements (including pH, conductivity, temperature, and turbidity) to $425 for specialized analyses; three bids were received, with Advanced Environmental Laboratories, Inc. submitting the low bid at $80,872.00 for a twelve-month initial term with four optional renewals. The City of Bradenton posted a notice of intent in July 2026 (26038NT) for WRF level sensors and controllers, initially as a sole-source procurement to The Avanti Company under its exclusive McCrometer representation agreement, though the City reserved discretionary authority to open the procurement to competitive bidding if respondents demonstrate capability to supply equivalent products. Solicitations are issuing from municipal water and wastewater utilities in Florida, with one procurement from the University of Wisconsin system for an oxygen consumption monitor and another from the City of Detroit for medical-grade oxygen supply—the latter two less directly aligned with the code's nominal scope but posted under this classification by the issuing bodies.

Geographic activity concentrates in Florida, where Palm Bay and Bradenton have solicited under the code in the past six months, with secondary activity in Wisconsin and Michigan. The issuing-body mix reflects municipal water and wastewater authorities as primary buyers, supported by university procurement systems and municipal services departments. Water and wastewater utilities dominate actual procurement volume under this code, driven by EPA and Florida Department of Environmental Protection regulatory monitoring requirements and compliance reporting mandates. The Palm Bay ITB represents ongoing annual demand—the City spent $66,360 in 2024 and $95,440 in 2025 on laboratory testing services—suggesting recurring, contract-based opportunities with unit-price structures and multi-year renewal options typical of municipal utility operations.
