PH regulation

pH is the measurement of the acidity of the water. The pH of a solution will continually vary depending on the environment. For a swimming pool, the ideal pH value is around 7.

To keep this value and thereby avoid any unpleasant effects, it is essential to stabilise it. To regulate the pH of a pool, a probe is fitted into the plumbing. Linked to a controller including a dosage pump, the probe measures the pH of the pool.

The controller compares the probe measurement with the programmed set point.  In the event of a difference, the controller injects the quantity of pH correcting agent required to bring it back to the set point.
