4.1 pH (ORP) electrode maintenance

4.
Fill the electrode with new internal solution (model
300), until it nears the filler port.
5.
Wash the tip of the electrode well with pure water
(deionized) and wipe it with filter or tissue paper.
6.
If the inside of the protective cap is dry, wash the
inside with pure water (deionized). After shaking out
the water, fill the cap with enough pure water
(deionized) to soak the sponge.
If the inside the protective cap of an electrode dries out and the
electrode is not used for a long period of time, the response speed
of the electrode may slow and its sensitivity may decrease.
