After cleaning, thoroughly rinse with deionized water and recalibrate if
necessary.
Normally, the conductivity measuring cell does not age. Special measuring
media (e.g. strong acids and bases, organic solvents) or temperatures that
are too high may considerably reduce its lifetime or lead to damage. The
warranty does not cover failure caused by measuring conditions and
mechanical damage.
We recommend to dispose of the measuring cell as electronic waste.

What to do if...
Cause
– No connection between meter
and conductivity measuring
cell
– Cable defective
– Measuring range exceeded
– Contamination in the area of
the electrodes
– Electrodes damaged
– The temperature sensor is not
immersed deep enough in the
measuring solution
– Temperature sensor
defective
Cleaning procedure
Immerse in acetic acid for 5 minutes (volume
share = 10 %)
Clean with warm water that contains wash-
ing-up liquid
Remedy
– Establish connection
between meter and
conductivity measuring
cell
– Make sure the correct
sensor is being used for
the application
– Clean the conductivity
measuring cell (see
section 3).
– Return the sensor
– Observe the minimum
immersion depth
– Return the conductivity
measuring cell
