Cleaning
Note
To clean the sensor, disconnect it from the instrument.
We recommend to clean the sensor thoroughly, especially before measuring
low conductivity values.
Contamination
Lime sediments
Fat/oil
After cleaning, thoroughly rinse with deionized water and recalibrate if neces-
sary.
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 war-
ranty does not cover failure caused by measuring conditions and mechanical
damage.
We recommend to dispose of the measuring cell as electronic waste.
Cleaning procedure
Immerse in acetic acid for 5 minutes (volume
share = 10 %)
Clean with warm water that contains wash-
ing-up liquid
