Smart ATO RO is a reliable device to fill your RO or RO/DI water reservoir automatically. When the water level falls down to the low-level sensor, it will fill the reservoir up to the high-level sensor. You can avoid TDS creep in the reservoir and always get clear RO or RO/DI water for your aquariums but never have to worry about forgetting to turn off your RO or RO/DI system causing catastrophic floods.
Smart ATO RO comes with two precise dual sensors along with a float ball switch which provide extremely protection to prevent accidental floods. The magnetic-mount dual sensors allow you to set them in variety containers effortlessly and are easily to move to another container.
