Cation conductivity Connected conductivity
sensor
Cation conductivity represents the sensor
downstream from the cation exchanger and
upstream from the "degassing module",
Degassed conductivity represents the sensor at
the outlet of the degassing module.
Measured value interrogation is obsolete as you
can only choose conductivity.

Dual conductivity
You can subtract two conductivity values and use the result to monitor the efficiency of an
ion exchanger, for example.
