Cleaning the Sensor

Keep the sensor as clean as possible for optimum measurement
accuracy. Frequency of cleaning depends upon the process
solution.
Note: Mechanical cleaning of the electrode surfaces may harm
Wipe the measuring end of the sensor with a clean with a clean soft
cloth. Then rinse with clean water (distilled or de-ionized if
possible). This should remove most contaminate buildup.
If necessary, soak the sensor for several minutes in a mild soap
solution. Use a small, extra-soft bristle brush (such as a mushroom
brush) to thoroughly clean the electrode surfaces.
deposits are not completely removed after performing this step, a
dilute acid may be used to dissolve the deposits. Soak for a few
minutes, and then rinse the sensor thoroughly with clean water
(distilled or de-ionized if possible).
Note: DO NOT soak the sensor in dilute acid solution for more
WARNING: ACIDS ARE HAZARDOUS. Always wear eye and
skin protection when handling.
Sheet recommendations. A hazardous chemical reaction can be
created when certain acids come in contact with process
chemicals. Make this determination before cleaning with any acid,
regardless of concentration. DO NOT use Hydrochloric Acid on
any stainless steel portion of the sensor.
After cleaning the sensor, check measurement and re-calibrate the
sensor.
