MAINTENANCE
Storage

Keep the sponge in the cap
soaked with tap water or pH 4 buffer solution
.
Do not allow sensor

.
3. Always rinse the electrode in deionized water between
measurements to avoid cross contamination. Double rinsing is
recommended when high accuracy is required.
4. Salt deposits may build up in the storage cap and should periodically
be rinsed away. These deposits could affect measurements at low
conductivity.
