Note on oxidising agents:
Oxidising agents such as calcium hypochlorite, chlorine, chlorine dioxide, sodium hypochlorite or
ozone above the limits permitted in "TrinkwV 2012" attack the dye contained in the reagent and
interfere with the measurement. This means that an exact determination of the water hardness is
no longer guaranteed. An activated carbon filter connected upstream of the analyser can remove
these oxidants from the sample water and thus enable the correct determination of the water
hardness.
The capacity of an activated carbon filter is consumed during operation. Therefore, the activated
carbon filter must be replaced at regular intervals. The effectiveness of the activated carbon filter
can be checked with the help of Caldur® test sets.
