Conductivity probes and measurement of conductivity :
The measurement of conductivity is done through a probe called conductivity cell that connected to the conductivimeter, plunged in the sample, the value measured is in µS/cm or mS/cm.
There are different cells for different range of measurements:
Cell with constant C=1, range of measurement 10 µS ... 10 mS
Cell with constant C=0.1, range of measurement 0,1 µS ... 1 mS
Cell with constant C=10, range of measurement 100 µS ... 200 mS
Like every physical parameter also the conductivity is influenced by the temperature variation so for this reason many conductivity cell include inside temperature sensor to compensate this variation.
Thanks to temperature compensation, it's possible to give a conductivity value at only one temperature of referement ( normally 20°C or 25°C) independent by real temperature of the sample.
