Zodiac pH Expert


The Zodiac pH Expert provides pH regulation for all types of in-ground pools up to 150m³ and can be installed in either an existing or a new build swimming pool.

The Zodiac pH Expert uses proportional dosing technology to maintain the pH in your swimming pool at a set point. The dosing time is automatically adjusted depending on the difference between the pH of your swimming pool and the pH set point.

The Zodiac pH expert can be used in conjunction with either the Zodiac TRI or EI salt chlorination systems, meaning it can extend the life span of the chlorinator and reduce the maintenance of the cell.

Range is 0 – 14 pH with an accuracy of +/- 0.1

Includes Probe & Fittings.

All installation fittings are included, with the exception of the chemical holding tanks.
