A substance in the water can disturb the ORP probe.
The default sensor in the product is a Platinum ORP sensor (Blue Sensor Pt). For example, some salt electrolyses produce free hydrogen which settles on the platinum probe and makes it blind.
If you have a salt pool, and are affected by this ORP problem, we recommend to:
- Avoid putting stabilizer or algaecide in your pool.
- Clean your probe with clean water.
- If the problem persists, consider purchasing a Gold Sensor called Blue Sensor Au (Contact your dealer). Gold sensor is not blinded by free hydrogen. The gold probe is only compatible with Blue Connect. It is not compatible with Blue by Riiot.
