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.
