Pentair 522186 pH Sensor for IntelliChem™ Systems

Part Number: 522186

Description

An OEM-grade replacement pH probe engineered for use with Pentair IntelliChem chemical automation controllers. Provides accurate, reliable pH measurement to help maintain balanced pool and spa water chemistry.

Compatibility & Fitment

  • Designed for use with Pentair IntelliChem system flow-cells and sensors.
  • Replace when the current pH probe is worn, no longer giving accurate readings, or if calibration fails repeatedly.
  • Direct replacement for systems originally equipped with part number 522186.

Features & Specifications

  • Probe type: pH sensor only (control cable sold separately).
  • Durable chemical-resistant housing, suitable for continuous pool/spa use.
  • Compatible mounting fits standard IntelliChem flow-cell sockets.
  • Backed by Pentair for reliable performance and ease of integration.

Installation Notes

Turn off the IntelliChem controller power and close flow cell isolation valves. Remove the old sensor, clean the flow-cell socket and apply fresh Teflon tape to threads. Install the new 522186 probe hand tight, restore valves, power up the system and calibrate per controller instructions to verify proper performance.

Maintenance Tip

Inspect and clean the probe regularly—rinse the tip, remove scale or oil film, and replace if readings remain erratic after calibration. A well-maintained probe helps ensure stable water chemistry and extends system life.
