MAINTENANCE
Care/Storage of Electrode
1. Always rinse the electrode in tap, distilled or deionized water between
measurements to avoid cross-contamination of the samples. Double rinsing is
recommended when high accuracy is required.
2. To preserve electrode life
keep the sponge in the protective cap soaked
with a pH 4 buffer.
Cap TRACER when not in use.
Store vertically
.
Do Not allow sensor to dry out.
3. Do not touch the electrodes. Touching the surface of the electrodes may damage
and reduce the life of the electrodes.
4. Salt deposits may build up in the storage cap and should periodically be
rinsed away. These deposits could affect measurements at low conductivity.
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.
