Hayward GLX-PROBE-PH Replacement pH Probe (Open Line) — Sense & Dispense / AQL-CHEM

The Hayward GLX-PROBE-PH is a genuine OEM replacement pH probe used to measure pool water pH in compatible Hayward chemistry automation systems. It restores accurate pH monitoring when your existing probe is old, drifting, slow to respond, or has failed.

Fits / Compatibility

  • Hayward Sense & Dispense chemistry systems: AQL-CHEM and AQL-CHEM-UPG
  • Also commonly listed for compatible Hayward salt chlorine/automation systems: AQR-PRO-SD and HPC-4-ACT-RC (verify your configuration/parts diagram)
  • Pool Type: In-Ground

What It Fixes

  • pH readings that drift or no longer match manual testing
  • Slow response to chemical changes or unstable pH display
  • Probe that is worn out, damaged, or has a compromised cable/connector
  • Chem automation that cannot maintain stable pH due to inaccurate sensing

Key Features

  • OEM Hayward replacement probe for reliable fit and signal compatibility
  • Designed for continuous pH monitoring in automated chemistry control systems
  • Direct-replacement style installation for supported Hayward Sense & Dispense setups

What’s Included

  • 1 GLX-PROBE-PH pH probe

Installation Notes

  • Turn off equipment power before servicing chemistry controllers.
  • Install the probe in the correct location in the sensing cell/sample stream as directed by your system manual.
  • After replacement, calibrate the pH probe using proper calibration solution(s) for accurate readings.
  • Keep the probe wet during handling; avoid letting the sensing tip dry out.

Maintenance Tips

  • Rinse the probe tip gently with clean water during service—do not scrub with abrasive materials.
  • Calibrate on schedule (and anytime readings drift from your reliable manual test kit).
  • Maintain balanced water chemistry to reduce scale buildup that can coat probes and affect accuracy.
  • If your readings become unstable, check sample flow through the sensing cell and inspect for air bubbles in the line.
