PENTAIR – IntellipH®

The IntellipH pH Controller automatically dispenses muriatic acid into the pool to protect pool equipment and make sanitizing more effective. IntellipH is the perfect companion for the IntelliChlor® Salt Chlorine Generator. Together, they help sanitize and balance pool water to keep it sparkling clear.
