K 100 (W) CL2 Measuring and Control Instrument for Chlorine
The K 100 (W) CL2 is a sophisticated single-channel instrument for measuring and control free chlorine. Additionaly temperature measurement of the measuring media is possible. The instrument is available in a panel mounted housing (K100 CL2) and in a wall mounted housing (K 100 W CL2).
Easy and safe operation by plain text menu guidance. Safety by password function.
Applications:
Drinking Water / Beverages, Disinfection, Cooling And Boiler Feed Water & Waste Water Treatment.

Accessories
ASR Cleaning. The cleaning is carried out electrochemically by electrolysis of water: H2O --> O2 + H2
The electrochemical cleaning acts threefold: the generated gases hydrogen and oxygen blast away even persistent coatings. Oxygen oxydises organic compounds, and hydrogen reduces rust and manganese oxide and likewise destroys organic coatings. The produced gas volumes are small and unused gas molecules recombine automatically to the water they stem from. The cleaning is activated in the menu of the measuring and control instrument. The starting time of cleaning can be defined by the user. The cleaning cycle lasts approx. 20 seconds. The measuring value is locked for five minutes, in the display, in the output signal, and also for the controller, to give the electrode time to polarize. The cleaning can be set to 0/1/2 times per day. ASR aims at keeping the sensor clean from the beginning. It was not meant to clean already coated sensors, since with those sensors the signals will be higher after cleaning, making a re calibration necessary.
