pH and Redox Electrodes
Typically, it is recommended to clean the electrodes when the response is slow or measurements are not reliable, and
when they have been used for a long time, especially in aggressive solutions, pollutants, very acidic or very alkaline
environments.
We provide 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)
