Incorporating all the functions of the eQuilibrium System, the eQuilibrium 2 Chlorinator has an pH sensor to maintain the perfect pH level. Different pool surfaces have different ideal pH levels. With the Viron eQuilibrium Chlorinator your pH is sensed every 15 minutes and the appropriate measure of pH adjuster is accurately dosed by the inbuilt peristaltic pump. Simply replenish your pH adjuster once a month or even longer and let Viron eQuilibrium 2 Chlorinator System sanitise and balance your pool water pH.
