Hanna, HI70022P, ORP test solution, 25x20 ml sachets

Our ORP test solution (HI70022P) is designed for testing the performance of ORP electrodes. When the ORP electrode is placed in the test solution the reading obtained should be close to the 470 mV 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, polished, and conditioned or replaced. The test solutions are produced in our state-of-the-art manufacturing facility using reagent grade chemicals in a temperature-controlled environment.
