UNSPSC 41115615: pH controller

A type of device that changes and appropriately adjusts the hydrogen ion concentration.

UNSPSC 41115615 pH controller is a Commodity code that appears in state and local procurement systems but does not map cleanly to the laboratory testing services state and local governments are actually soliciting under it. The code's nominal scope — a single equipment item — does not align with the substantial analytical and compliance-testing contracting activity visible in recent solicitations. When the code does appear in state and local records, it is typically embedded within much broader environmental laboratory service procurements that encompass water quality testing, wastewater analysis, groundwater monitoring, and industrial pretreatment compliance across multiple facilities and regulatory domains.

The City of Palm Bay, Florida issued Invitation to Bid 19-ITB-26 for comprehensive laboratory testing services in April 2026 with a response deadline of March 17, 2026. The scope spanned 188 line items across water testing, wastewater testing, industrial pretreatment analysis, and courier services for three wastewater treatment facilities, two water treatment facilities, groundwater monitoring wells, and permitted industrial pretreatment programs. Bidders were required to hold Florida Department of Health Environmental Laboratory Certification Program certifications and NELAP accreditation, with 75 percent of analytical work performed in a primary laboratory located within one hundred miles of the City's North Regional Campus. Three bids were received: Advanced Environmental Laboratories, Inc. at $80,872.00; Flowers Chemical Laboratories, Inc. at $91,775.40; and Pace Analytical Services, LLC at $107,946.10. Unit prices for individual tests ranged from $0 for field measurements such as pH and temperature to $425 for specialized analyses, with the City's historical spending of $66,360 in 2024 and $95,440 in 2025 establishing budget context. The code shows limited recent activity as a discrete procurement category; opportunities under it tend to reflect broader environmental laboratory service solicitations rather than pH controller procurement as a standalone commodity.
