Description
The Neptune MOS replaces the previous OS-1-M and features a redesigned structure that fits into smaller spaces and helps prevent water from entering the sensor. The MOS connects to an Apex FMM port and uses reflected infrared light to signal your Apex when the state changes from wet to dry or from dry to wet. This sensor can be used for building your own ATO (auto-top-off), as a high-level warning sensor in your sump, water storage level sensor, and much more. The sensors can be mounted on any type of reservoir with walls up to 1/4″ thick.
