The pH level indicates the level of water acidity which is important for water quality. A constant pH value is a precondition for the correct operation of other water treatment systems such as filtration and disinfection. Furthermore, the correct pH value is important for preventing skin irritation. The Starline pH dosing pump measures and maintains the water's pH level. A sensor measures the pH value, after which pH+ or -pH - is added to the water. This depends on the lack or surplus of pH. The pH level maintenance takes place entirely automatic with the Starline pH dosing pump, which means you can always rely on safe swimming pool water of an excellent quality!
