HI7022M is an ORP test solution designed for testing the performance of platinum and gold ORP electrodes. When the ORP electrode is placed in the test solution the reading obtained should be within +/- 50 mV of the 470 mV @ 25°C value. This solution allows users to quickly see if their electrodes are reading correctly. Using this as a diagnostic tool, users can then decide if the ORP electrode needs to be cleaned and conditioned.
