C4E Conductivity Sensor electrode technology:
The sensor works with 4 electrodes: An alternating current of constant voltage is established between a primary pair of electrodes in graphite. The secondary electrodes in platinum regulate the voltage imposed to the primary electrodes to reflect the fouling. The voltage measured between the primary electrodes is the function of the resistance and therefore a measurement of the conductivity.
C4E Conductivity Sensor Digital Technology :
The smart digital C4E sensor stores calibration history data within the sensor. This allows a 'plug and play' system without re-calibration.
