Those cells are designed for the survey or regulation of Chlorine in swimming pool or chlorination process.
Water and process characteristics for measurement:

• Free of oil and grease.
• Constant pH between 6.5 and 8 pH.
• Constant Temperature with a maximum of 40°C.
• Constant Conductivity.

The reaction cell includes a Cu/Pt pair of electrodes. It delivers an electric current, proportional to the concentration of free active chlorine and then amplified by a transmitter. This basic measurement guarantees a high accuracy and perfect reproducibility.

The electrodes are permanently cleaned with a continuous movement of small glass balls. The sampled water circulation creates the glass balls movement, adjustable with the integrated regulation valve.
