The 222mV ORP standard solution is used for checking and treatment of ORP electrodes. To check the function of an electrode, immerse the electrode in the ORP solution (in a separate vessel). The measured mV value should not deviate by more than +/- 15mV from the value indicated on the bottle (at your temperature). If the reading is not within +/- 15mV, immerse the electrode in the 222mV standard solution for 15-30 minutes for treatment. It will prepare the electrode’s surface for measurement and speed up the response time of the electrode.
Contains 250ml standard solution with an ORP value of 222mV (at 25°C)
A table of the ORP value at different temperatures can be found on the label
Use immediately: Instead of dissolving powder in distilled water first, you can use this solution immediately
