Maintenance of the Redox Electrode
Typically, it is recommended to clean the electrode when the response is slow or measurements are not
reliable, and when it has been used for a long time, especially in aggressive solutions, pollutants, very
acidic or very alkaline environments.
STEIEL provides a kit of solutions for the cleaning and storage of pH and redox electrodes.
The kit includes three solutions:
Solution A: dip the electrode in this solution for cleaning it
-
Solution B: use this solution to rinse the electrode, before and after cleaning
-
-
Solution C: storage solution to be used for filling the electrode protective cap when the electrode is not
used (wintering, closure of the plant)
