Pentair pH Sensor for IntelliChem Chemical Controller | 522186Z

Description

The Pentair pH Sensor (522186Z) is the OEM replacement pH sensing electrode for the Pentair IntelliChem® Chemical Controller.

The pH sensor continuously monitors pool and spa water chemistry, transmitting real-time pH readings to the IntelliChem® controller. When the sensor degrades or drifts out of calibration range, pH dosing accuracy is compromised — resulting in under- or over-treatment of the water. Replacing the sensor with the correct OEM part restores accurate chemical feed control. Match the part number on your existing sensor or your IntelliChem® documentation before ordering.

Pro Tip

pH sensors have a finite service life — typically one to two years depending on water conditions and usage frequency. If your IntelliChem® controller is reading pH erratically or consistently off from a manual test, calibrate the sensor first using the controller’s calibration procedure. If accurate calibration cannot be achieved, sensor replacement is the correct next step. Keep the sensor port free of scale buildup during routine equipment maintenance to extend service intervals.
