Long-term storage
When an electrode will not be used for a long period of time, store it after performing the fol-
lowing procedure. Also, perform maintenance on the electrode every three to six months.
1. Remove the electrode from the pH meter.
2. Use pure water to wash away any sample solution that may have adhered to
the electrode.
3. Wash the inside of the electrode protective cap with pure water, then, after
shaking out the water, fill the cap with enough pure water to soak the sponge.
4. Place the electrode protective cap on the electrode.
