Automatically monitor and maintain the chemical balance in your pool and spa

Watermatic controllers automatically monitor and maintain the chemical balance in swimming pools and spas.

Designed for easy installation and operation, they can be used with liquid feed pumps, granular and tablet erosion feeders, ozone generators, and salt chlorinators.

During the filtration cycle, the controller maintains sanitizer levels and pH balance by constantly measuring the Oxidation- Reduction-Potential (ORP) and pH balance of the water. If the sanitizer level (ORP) or pH falls below a predetermined set point, the controller activates the chemical feeder.
