Chlorinator by Measuring Water Free Chlorine

Chlorinator depending on the measured free chlorine Cl2 value (with potentiostatic probe) for medium and large private or public drinking water. Complete system on panel with instrument for chlorine, analogue dosing pump, potentiostatic probe for chlorine, probe holder and flow sensor.

Flow rate up to 54 l/h.
Pressure max 20 bar.

Typical Installation


Compact system for measuring and adjusting the chlorine in private or public drinking water systems. Analogue dosing pump with instrument for measuring free chlorine value of the water. Ideal to treat water systems where the water quality is variable and demand very sensitive corrections.


Pre-installed system on panel or cabinet ready to use. The unit include intelligent instrument for free chlorine, analogue digital dosing pump, potenstiostatic electrode for the measure of free chlorine and probe holder with flow sensor for reliable and safe operation.


Set the value of Redox depending on the concentration of residual chlorine. The concentration of free chlorine in the tank being such as to provide a free chlorine in the water supply net at least 0,2 mg/l (ppm).


Key Point

For proper chlorination of water is important a reliable measurement of the Free Inorganic Chlorine value:


  • Good mixing of chlorine to water.
  • Proper contact time chlorine-water.
  • Correct point for water sampling.
  • Good maintenance of the electrode (clean).
  • Regular calibration of the electrode.
