Apera ORP Standard Solution 220mS/Cm

The ORP standard solution 220mS/cm is used for checking and regenerating ORP electrodes.
For functional testing, immerse the electrode in the ORP solution in a separate container. The measured mV value must not deviate by more than ± 15 mV from the value specified on the bottle (at your temperature). If the value is outside this ± 15 mV range, leave the electrode in the 220 mV standard solution for 15–30 minutes. This prepares the electrode surface for measurements and shortens the response time.

• Content: 250 ml standard solution with an ORP value of 220 mV (at 25 °C)

• A table with ORP values at different temperatures can be found on the label.

• Ready to use immediately: You don’t need to dissolve any powder in distilled water; you can use the solution directly.
