Pentair pH Sensor | IntelliChem Chemical Controller | 522186

Description

The Pentair pH Sensor (522186) is the OEM replacement pH sensor for the Pentair IntelliChem Chemical Controller, designed to continuously monitor water pH levels and provide accurate readings to the IntelliChem system for automated chemical dosing.

The pH sensor interfaces directly with the IntelliChem Flow Cell, delivering real-time pH data to the controller. Accurate pH measurement is essential for effective chemical management — a failed or drifted sensor causes the IntelliChem system to dose incorrectly, leading to water imbalance, equipment corrosion, or ineffective sanitization. Replacing the sensor on schedule restores measurement accuracy and keeps automated chemical control operating within specification.

Specifications

Fits Into

Compatibility is based on Pentair parts documentation and available OEM records. This is not an exhaustive list. For certainty, verify the part number in your equipment’s manual or on the original part itself before ordering.

Pro Tip

pH sensors have a finite service life — electrode degradation causes calibration drift over time even when the sensor appears physically intact. If your IntelliChem system is requiring increasingly frequent calibration adjustments or displaying erratic pH readings that don’t respond to calibration, the sensor is the first component to replace. Check the manufacture date stamped on your existing sensor and compare it against your service records before ordering to confirm this is the correct replacement interval.
