Measurement and injection tube with 4 holes 1 1/2 inch with flow switch connection

Using a gold probe is absolutely necessary for salt electrolysis.

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

This black RX probe with gold interior will be able to measure the Redox of salt electrolysis pool water for several years. Redox is a measure of the oxidation power of the pool: the higher the redox, the more free chlorine 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 and is usually installed via a 1/2 inch probe holder in the pipe.

The probe needs to be calibrated once a year (against a calibration solution of 468 mV).
After calibration, the ideal redox value for 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 (when the pH is between 7.2 and 7.6), using a high-quality chlorine meter.
If the chlorine content is lower than 0.8 - 1.2 ppm, the redox target should be increased.
If the chlorine content is higher than 0.8 - 1.2 ppm, the redox value should be lowered. A good Redox probe will measure between 600 and 800 mV at 1 ppm chlorine.

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

Thanks to the rubber seals, it is not necessary 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
