Conductivity Electrode Care and Maintenance
•
DO NOT touch the measurement area of electrode and always make sure that is clean.
•
If there is a build-up of solids inside the measurement area, these should be removed very carefully with a cotton bud soaked in solvent, taking care
not to touch the metal parts of the inner cell. After the solids are removed, the electrode must be recalibrated.
