Hanna ORP - Replacement Electrode
Product Code: HI73120
The Hanna HI73120 Replacement ORP Electrode is a direct replacement electrode for the Hanna HI98120 waterproof ORP and temperature handheld meter. Designed as an easy-fit cartridge, the HI73120 allows a worn or damaged ORP sensor to be replaced without purchasing a new meter.
The HI73120 uses a platinum sensing pin for oxidation-reduction potential measurements and a single Ag/AgCl reference system with a cloth junction and gel electrolyte. Two O-rings provide a watertight seal when the electrode is installed in the HI98120 tester.
The replacement electrode has an ORP measurement range of ±2,000 mV and is designed for general-purpose and field ORP applications. It operates over a temperature range of -5 to 50°C (23 to 122°F).
