Polishing the chloride electrode
Caused by the test medium, a coating can develop on the surface of
the chloride electrode, which reduces the electrode slope. To maintain
a proper chloride compensation the surface must be renewed by
polishing at regular intervals.
Caution
Danger of damaging the electrode. Exclusively use the SF 300
polishing strip. Never use commercial sandpaper or similar.
The polishing can be done while the electrode is mounted (remove the
protective hood as necessary). To polish the electrode, use the SF 300
polishing strip provided with the electrode. Moisten the rough side of
the polishing strip with water and polish off any coatings under slight
pressure.
