Zodiac - pH Electronic Board for TRi pH & pH Link - W083001

Zodiac – pH Electronic Board for TRi pH & pH Link

This is a genuine Zodiac replacement pH printed circuit board (PCB) for the TRi pH module and pH Link system. It is the core control component responsible for reading pH sensor data and managing the automatic dosing pump that keeps pool water in balance. Replacing a faulty board restores full automated pH regulation without the need to replace the entire pH module.

Compatibility

Designed specifically for the Zodiac TRi pH and TRi PRO salt water chlorinator modules (Fluidra exploded view W197525), as well as the Zodiac pH Link system. It is not a universal PCB and will not fit other Zodiac chlorinator models or pH controllers outside this range. Always verify your model before ordering.

Why genuine matters

As an original Zodiac spare part sourced directly through Fluidra, this PCB is manufactured to the exact electrical tolerances of the TRi pH system. A genuine board ensures accurate pH measurement (0.0–12.0 range), reliable peristaltic pump control, and correct sensor calibration routines — all of which can be compromised by non-OEM alternatives.

Installation

The pH PCB is located inside the TRi pH module housing and is secured with small screws. The board should be replaced by a qualified pool technician or competent installer, as the work involves disconnecting low-voltage wiring and handling sensitive electronics near water. Always isolate the system from its power supply before opening the module.
