MAINTENANCE
Care/Storage of Electrode
1. Rinse the electrode in distilled or deionized water.
2. Store the electrode with the cap on.
Keep the sponge in the cap
soaked with tap water or pH 4 buffer solution
.
Do not allow
sensor to dry out. Store upright
.
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.
Electrode Cleaning Recommendations
Do not soak the electrode in the solutions for longer than the
recommended length of time. To do so may cause a reference potential
shift which will cause a degradation in performance or failure. When
cleaning the electrode, take care not to scratch or damage the sensing
surface or the platinized electrode surfaces. To remove water soluble
contaminants from the electrode, soak the electrode in deionized water
and scrub with a soft brush. Recondition in pH 7 buffer for 1 hour.
Battery Replacement
1. Twist off the battery compartment cap.
2. Hold the battery housing in place with one
fi
nger. Remove the
battery carrier by pulling on the small tabs.
3. Replace the four CR2032 batteries. Observe polarity.
4. Replace the battery compartment cap.
