III. Maintenance
Clean the sensor before use, especially when measuring low conductivity
solutions. The power should be disconnected before cleaning.
For cleaning mineral deposits, immerse the sensor in acetic acid for 5
minutes. Other types of contamination such dirt and oil can be cleaned using
mild soapy water.
Normally the conductivity sensor does not age and will not require periodic
calibration. Measuring strong acids, bases or organic solvents can
considerably reduce the sensor’s lifetime or cause permanent damage. Long
term exposure to very high temperatures may also damage it. These types of
damage are not covered under warrantee.
IV. Trouble Shooting

d. Make sure the conductivity and temperature of the solution is within
the measurement ranges of the sensor
e. Clean the sensor according to the guidelines described in the
Maintenance section
f. Ensure that the minimum immersion depth is maintained or incorrect
conductivity and/or temperature readings can result
