The lifespan of an electrode varies depending on its use and maintenance.

To optimize the longevity of the electrodes, there are 3 rules to follow:

1. Rinsing : Rinse with tap water after each measurement.
2. Storage : Store the electrode upright and always put a few drops of storage solution in the protective cap.
3. Calibration : Use the intended calibration solution and adjust the measuring device according to its operating instructions.
