Electrochemical chlorine sensor CC1

for water treatmentfor process measurementIP65

Product information
German-made CC1 free chlorine sensor adopts a membrane-covered amperometric potentiostatic 3-electrode system with built-in electronics. It measures free chlorine, features automatic temperature compensation, requires no zero-point adjustment, and has highly reduced pH dependence. It is mainly applied to swimming pool water, drinking water, and sea water.

Technical characteristics
This residual chlorine sensor offers good measurement stability, practical operation and maintenance, strong environmental adaptability, flexible signal and connection options, and complies with EMC and RoHS standards.

• Swimming-pool water
• Drinking water
• Service water
• Process water
• Sea water

Ambient conditions

• Max. temperature: 45 °C
• Max. pressure: 3 bar
