Product Details
- Product Name: Gold Disk ORP Sensor Industrial Pool and Spa Water Chemical Controller Probe
- Product Type: ORP sensor / chemical controller probe
- Use For: Pool and spa water chemical controller systems
- Compatibility Notes: Listed as Acu-Trol compatible and for salt water systems/chlorine generators
- Connection Style: Standard 1/2 inch NPT connection listed
- Main Use: Helps measure ORP levels for supported water chemistry control systems
- Installation Type: Inline probe installation for compatible controller setups
- Best For: Replacing an existing ORP probe in pool or spa chemical automation systems
- Important Note: This is a replacement sensor probe, not a complete chemical controller or salt chlorine generator
ORP Sensor Use
This probe is used with supported pool and spa chemical controllers to help monitor sanitizer activity through ORP readings. If you are comparing a Hayward ORP probe, make sure the connection style, controller model, and installation location match your current system before buying.
ORP readings can be affected by water balance, probe condition, flow, contamination, and controller calibration. Always follow the controller manufacturer’s instructions for setup and testing.
Compatibility and Controller Notes
This sensor should be matched with the exact chemical controller or automation system already installed. It should not be chosen only by appearance because similar probes can have different connectors, thread types, or calibration requirements.
For systems that also monitor pH, a separate Hayward pH probe may be required. ORP and pH sensors serve different functions, so one should not be used as a substitute for the other.
Salt System and Chlorine Generator Use
This probe may be used in compatible setups connected with salt-based pool sanitation equipment. If your pool uses salt water systems, confirm that the ORP controller, salt generator, and water chemistry settings are designed to work together.
When used around salt chlorine generators, the probe should be installed in the correct plumbing position with steady water flow. Incorrect placement can lead to unstable readings or poor controller performance.
Before You Buy
Choose this product only if you need a replacement ORP sensor for a compatible chemical controller. If the controller is showing unusual readings, also check water balance, calibration, probe age, wiring, and flow before assuming the sensor alone is the problem.
Review the product image, probe body, connector, thread size, compatibility list, and return policy before ordering because sensor parts must match the existing controller setup closely.
