The HYDROS Triple Optical Water Level Sensor can be used for a variety of aquarium applications, such as sensing when your tank needs to be topped off or detecting when a dosing container needs a refill. It plugs into any Sense Port on a HYDROS device (like the Control XS, X2, X4, X10, etc.) and does not require any additional power source.

The HYDROS Water Level Sensor contains no moving parts that can fail. The optical eye is magnetically coupled with the magnet side measuring only ¼” thick. It can be mounted to most clear, tinted, or painted surfaces up to ½” thick. The sensor operates in the daytime or complete darkness so it’s safe for use hidden inside your aquarium stand or in the back chambers of an all-in-one aquarium. The sensors are easy to place, easy to move, and easy to clean.
