Low cost and easy to use swimming pool residual chlorine controller

Residual chlorine concentration controller CL-60WL

Contact us | PDF Catalog (PDF: 190KB)

Residual chlorine concentration controller CL-60WL • No wasted water because of inline type flow cell

• Thanks to 3-electrode polarograph sensor, it is not influenced by impurities in test water or conductivity and gives superior linearity.

• Multi-voltage power source from AC90 to 240V.

• Electromagnet metering pumps can be directly controlled (proportional dosing) by the pulse control output.

• Flow cell is easily removed for maintenance.

• Pump control output can be manually interrupted during abnormal conditions to prevent excessive chlorine injection.

• Flow proportional control of the dosing pump is possible by proportional DC4-20mA input signals from a water meter installed in the main water piping.

• Override function allows pump operation at maximum speed (360 spm with electromagnet metering pump) by contact input during super chlorination or pump maintenance.

• Alarm output can be set optionally (1a x 3)
