Electrode Maintenance

1. Inspect the electrode for scratches, cracks, salt crystal

buildup, or membrane/junction deposits.

2. Rinse off any salt buildup with distilled water. Remove any

membrane/junction deposits as directed in the General

Cleaning section.

3. If the electrode is reﬁllable, drain the reference chamber,

ﬂush it with fresh ﬁlling solution and reﬁll the chamber with

fresh ﬁlling solution.

4. If the electrode is reﬁllable, make sure that the ﬁlling

solution does not crystallize or dry out. Remove any

crystals by rinsing the electrode with distilled water

or wiping with a damp, lint-free tissue. To prevent

crystallization of the ﬁlling solution, cover the ﬁll hole

whenever the electrode is being stored and open the ﬁll

hole when calibrating and measuring.
