The HYDROS Leak Detection Sensor is a reliable device designed to protect your saltwater aquarium from water leaks by detecting when liquid comes into contact with the sensor surface. It can be easily integrated with other HYDROS OS devices such as Control 2 or Control 4, allowing you to program specific actions in case of a leak detection event, like turning off pumps or sending an alert to your smartphone. The sensor is encased in a rust-proof seal, ensuring durability and long-term use without the need for frequent replacement.
