Pentair IntelliChem ORP Sensor | Chemical Controller | 522187Z

Description

The Pentair IntelliChem ORP Sensor (522187Z) is the OEM replacement oxidation-reduction potential sensor for the Pentair IntelliChem® Chemical Controller.

⚠️ IMPORTANT: LICENSED PROFESSIONAL INSTALLATION REQUIRED
Electrical control components must be installed or replaced by a qualified electrician or certified pool technician.

The ORP sensor continuously measures the oxidative capacity of the pool water and reports that reading to the IntelliChem controller, which uses it to regulate sanitizer dosing. When the sensor degrades or drifts out of calibration range, the controller can no longer accurately manage water chemistry. Replacing the sensor with this OEM part restores accurate ORP measurement and reliable automated chemical control. Match the part number 522187Z to the sensor installed in your IntelliChem unit before ordering.

Pro Tip

ORP sensors have a finite service life and should be replaced periodically as part of routine IntelliChem maintenance — even if the controller does not throw an error. If your IntelliChem is dosing inconsistently or the ORP reading appears flat or unresponsive to known water chemistry changes, sensor replacement is the appropriate first step. Verify the part number on your existing sensor before ordering to confirm 522187Z is the correct replacement for your controller version.
