How can the performance of ORP (redox) Electrodes be checked?
The performance of an ORP electrode can be determined either by measurement in specially prepared buffer solutions saturated with quinhydrone or with ready-to-use Reagecon Redox Standard (e.g. Redox Standard 250 mV @ 25°C, Cat No. RS250). When the electrode responds properly, calibration is unnecessary. However, the electrode may become contaminated and give erroneous readings. Hence, it is desirable to check the performance of redox electrodes using a Reagecon Redox Standard.
