Hanna HI4003 Cadmium Half-Cell Ion Selective Electrode

Hanna HI4003 Cadmium Ion Selective Electrode – Solid-State Half-Cell Sensor for Cadmium Detection

The Hanna HI4003 Cadmium Half-Cell Ion Selective Electrode is a solid-state ion-selective electrode (ISE) designed for the detection and monitoring of cadmium ions (Cd²⁺) in aqueous solutions. This half-cell electrode provides sensitive and accurate measurements over a wide concentration range and must be used with a separate reference electrode.

Ideal for use in titration analysis, wastewater testing, and metal plating quality control, the HI4003 offers precise results even at low concentrations. Its rugged epoxy body ensures durability in both laboratory and industrial environments.
