 On site measurements in rivers, lakes and wastewater
 Fish farming
 Ground water measurements
 Applications in water laboratories
CAUTION
To clean the sensor, disconnect it from the instrument.
We recommend to clean the sensor thoroughly, especially before measuring low
conductivity values.
Contamination Cleaning procedure
Lime sediments Immerse in acetic acid for 5 minutes (volume share =
10 %)
Fat/oil Clean with warm water containing washing-up liquid
After cleaning, thoroughly rinse with deionized water and recalibrate if
necessary.
Normally, the conductivity measuring cell does not age. Special measuring
mediums (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 cases where such conditions cause failure or mecha-
nical damage.
