HI7021L is an ORP test solution designed for testing the performance of ORP electrodes. When the ORP electrode is placed in the test solution the reading obtained should be within +/- 50 mV of the 240 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. The test solutions are produced in our state-of-the-art manufacturing facility using reagent grade chemicals in a temperature controlled environment.
