7.2.6 CTZN sensor: Inductive conductivity.
Conductivity: inductive measurement technology;
Temperature: NTC thermistor.
EPDM, PVC, 316L stainless steel (sleeve protecting the temperature sensor);
polyurethane sleeve on cable.
This measuring technology is not sensitive to fouling. However, ensure that
the loop is not obstructed.
When immersing the sensor in the medium to be measured, wait until the
sensor's temperature has stabilized before taking the reading.
The sensor is not well suited to measuring in the weakest ranges (0-200
µS/cm).
After each use, rinse the sensor carefully in clean water.
The sensor should be dried before being stored.
Using a clean sensor, perform a 2-point calibration of the sensor (offset and
gain using a standard solution whose conductivity is suited to the average
value expected):
