Maintain the Perfect pH in Your Pool

The pH balance of your pool and spa is crucial to maintaining a safe, healthy and comfortable swimming environment. pH is a measure of the balance of Alkalines and Acids in your water, and if out of balance, the water may cause stinging of the eyes, lower sanitiser effectiveness and promote the growth of algae and bacteria.

The RolaChem RP9 automatic pH controller measures the pH and then adjusts it with a measured dose of pH adjuster. This keeps your pool safe, looking great and healthy. With sophisticated sensors and software programming, the pH level is continuously monitored and adjusted taking into account weather conditions or bather load.
