ORP logger sensor NUL-258

The NeuLog ORP (Oxidation Reduction Potential) sensor can be used to quantify whether a substance is a strong oxidizing agent or a strong reducing agent. For example, the ORP electrodes are used to measure the oxidizing ability of chlorine in swimming pools.

The electrode has two components: a measuring half-cell comprised of platinum metal immersed in the solution in which the redox reaction is taking place, and a reference half-cell (sealed gel-filled Ag/AgCl) to which the platinum half-cell is referenced.
