- direct installation on the sensor - approaching flow to the sensor through RV1 - cleaning effect of RV1 is moderate, i. e. weak deposits on the electrodes will be removed, e. g. weak rust films - for a correct and proper operation of sensor with cleaning equipment RV1 flow chamber FLC-3 has to be used!! - Sensor can be upgraded at any time - Using with AS...-CL: => slope is approx. 3 times higher (see diagram “AS-Chlorine Sensor with and without RV1”) - Using with AS...-CD: => slope is approx. 2 times higher (Subject to technical changes.)
