Redox based systems indicate the Oxidation Reduction Potential (ORP) of the water (sanitiser activity), but not the quantity of sanitiser present. ORP can be used to control a set point to safeguard bathers. As with all ORP based systems, it is vitally important to ensure the body of water is balanced prior to commissioning the equipment. Once the body of water is balanced (key aspects being pH; free and combined chlorine) the mV reading given should be used as the set point for the controller. The systems shown offer an economical method of monitoring pool water quality and are best suited to domestic applications.
