RX probe Platinum + tapping saddle + gland DIY kit

This platinum probe is not suitable for salt electrolysis treatment.

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

This black RX probe with platinum interior will be able to measure the Redox of salt electrolysis pool water for several years. Redox is a measurement of the oxidation power of the pool: the higher the redox, the more free chlorine there is in the pool water.

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, usually installed in the pipe with a 1/2 inch probe holder.

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

We advise storing the probes in KCl storage solution during winter. During calibration and/or winter, you can seal 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
