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.
