Using a gold probe is absolutely necessary for salt electrolysis.

This black RX probe with gold interior will measure the Redox of salt electrolysis pool water for several years. Redox measures the oxidation power of the pool: the higher the redox, the more free chlorine is in the pool water.

In salt electrolysis, a standard (platinum) probe is poisoned by the hydrogen released during electrolysis, hence the need to use a gold probe.

The probe has a standard BNC connection and is interchangeable with probes from most other brands.
The probe has a diameter of 12mm and is 120mm long and is usually installed via a 1/2 inch probe holder in the pipe.

The probe must be calibrated once a year (against a calibration solution of 468 mV).
After calibration, the ideal redox value of the pool must be determined. This value depends on several factors and varies for each pool.
This is done by measuring the chlorine content in the pool (while the pH is between 7.2 and 7.6) using a good quality chlorine meter.
If the chlorine content is below 0.8 - 1.2 ppm, you need to increase the redox target value.
If the chlorine content is above 0.8 - 1.2 ppm, you need to decrease the redox value. With a good Redox probe, the measured redox at 1 ppm chlorine will be between 600 and 800 mV.

We recommend storing the probes in KCl storage solution during winter. During calibration and/or winter, you can close the probe connection with dummy probes. The probe must always be kept moist.

Thanks to the rubber seals, there is no need to use Teflon or thread tape in the drilling saddle or union.

The probe is supplied with:

  • 1/2 inch probe union
  • Matching 50mm drilling saddle
