- Package contents: Confirm included items before publishing
- Best for: Replacing a worn, damaged, dirty, or misreading ORP probe
- Buyer note: Verify the existing probe part number, connector style, and controller compatibility before ordering
Compatibility Notes
Use this probe when your Hayward Sense and Dispense system needs an ORP sensor replacement. If your controller is showing chemical reading issues, confirm whether the problem is with the ORP probe, pH probe, wiring, calibration, water balance, or flow through the sensing chamber before replacing parts.
For pH monitoring on the same automation setup, check the pH probe for Sense and Dispense before replacing the ORP probe by mistake.
If you are replacing more than one automation component, review the Hayward Sense and Dispense automation system to confirm the correct setup before ordering.
For other chemical controller sensor options, compare the ORP sensor parts before ordering.
What the ORP Probe Does
ORP stands for oxidation-reduction potential. In pool automation, the ORP reading helps the system understand sanitizer activity in the water. A worn, dirty, damaged, or misreading probe can cause inaccurate readings, which may lead to poor chemical control.
Replacing the probe may help restore more reliable ORP monitoring when the existing probe is no longer responding correctly or cannot be calibrated properly.
Installation and Setup Notes
Turn off power to the pool automation system before removing or installing the probe. Follow the Hayward system manual for the correct installation location, wiring connection, and calibration steps.
After installation, allow the probe time to stabilize in the water. ORP readings can be affected by water balance, sanitizer level, cyanuric acid, pH, probe cleanliness, and flow through the sensing chamber.
If the controller also shows flow warnings, check the Hayward flow switch before assuming the ORP probe is the only problem.
If your automation readings are inconsistent across multiple sensors, a separate temperature sensor replacement may also need to be checked.
Maintenance Tips
Keep the probe tip clean and avoid scratching or touching the sensing surface. Do not use harsh tools to clean the probe. Inspect the cable and connector for damage before installation.
If the probe has been stored dry, exposed to freezing conditions, or has visible damage, verify whether it is still usable before installing it. Follow the manufacturer’s storage and calibration guidance for best results.
Before You Order
- Confirm your old probe part number is GLX-PROBE-ORP.
- Make sure your system needs an ORP probe, not a pH probe.
- Match the connector, cable, and probe shape with your existing part.
- Confirm compatibility with your Hayward Sense and Dispense system.
- Check water balance, flow, calibration, and wiring before replacing the probe.
Do not order this part if you need a full automation system or salt chlorine generator.
