PH electrode storage solution, 500 ML product number: 2756549

The California Department of Fish & Wildlife awarded a Non-IT Goods contract to Preferred Suppliers LLC on August 20, 2026, with a total contract value of $3,598.81. The contract encompasses laboratory and field testing equipment and supplies essential for water quality analysis and monitoring operations. The primary deliverable is an HQ4300 portable multi-meter capable of measuring pH, conductivity, total dissolved solids (TDS), salinity, dissolved oxygen (DO), oxidation-reduction potential (ORP), and ion-selective electrode (ISE) parameters across three channels, valued at $2,913.00.

The contract also includes calibration and maintenance materials to ensure accuracy and reliability of the multi-meter and related laboratory instruments. These supporting items consist of pH electrode storage solution, a color-coded buffer solution kit with pH standards of 4.01, 7.00, and 10.01, traceable conductivity calibration standards certified as reference materials with National Institute of Standards and Technology (NIST) testing, and laboratory wipers for delicate task applications. The cumulative value of these ancillary items totals $685.81, collectively enabling the Department to conduct comprehensive water quality monitoring and analysis activities in compliance with established calibration and testing protocols.
