13.1. ELECTRODE CARE & MAINTENANCE
Proper care and maintenance of the conductivity probe is essential for accurate readings. Cleaning,
calibrating, and appropriate storage will extend the life of the probe.
1. As preventative maintenance measure, rinse the probe with tap water on a weekly basis. Monthly,
a more thorough cleaning is advised. Clean the EC sensor with a non-abrasive detergent, or refer
to cleaning step 4 below.
2. Inspect the inside portion of the probe where the two electrodes (prongs) are. It should be free
of foreign material.
3. If any solids are detected in this area, use a soft material such as Q-tip, to dislodge the material.
Pass repeatedly the Q-tip between the two pins and inner surface. DO NOT BEND PINS!
4. Salt or mineral coating can be removed by rinsing it under a stream of running tap water and
jetting the stream into the cell.
5. Shake excess water from the probe.
6. Recalibrate: place the probe into EC calibration standard. See section 10 MAINTENANCE.
7. The probe should be clean before is stored for any length of time. Clean the probe and place it
into its box for storage.
