Product Overview

The Pentair IntelliChem® ORP Sensor (Model 522187) is a genuine replacement oxidation-reduction potential (ORP) probe designed for the Pentair IntelliChem Water Chemistry Controller. This sensor continuously measures ORP levels in real time, allowing IntelliChem to precisely regulate sanitizer output—ensuring balanced, safe, clear, and consistently clean pool water.

Engineered for accuracy and reliability, the ORP Sensor is essential for maintaining automated chemical control in chlorine or bromine-based pools and spas.

Ideal For

• Existing IntelliChem® systems needing a replacement ORP probe

• Pools and spas using automated chemical regulation

• Ensuring proper sanitizer levels for residential or commercial installations

• Pool owners wanting consistent, hands-free water chemistry management
