Concentration curves / ranges
see page 112 et seq.
The concentration curves of many sub-
stances show a maximum. This means that
if the substance concentration continues to
increase and the temperature remains con-
stant, the conductivity will drop. Therefore,
a one-to-one correlation of values is only
possible in defined ranges.
These partial ranges must be selected as
measurement ranges in the configuration.

Ranges for sulfuric acid
