240 mV @ 25°C ORP Test Solution (500 mL)

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 +/- 20 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.
