Puratek Non-intrusive Level Sensor

This non-intrusive level sensor attaches to the outside of aquarium or sump.  It senses the absence or presence of water through the glass or acrylic and is not exposed to the harsh environment directly. It is completely solid state with no moving parts for long lasting life.  No need to worry about sensor sticking as mechanical sensors can and roaming snails or crabs will not interfere with the operation.
