The SMART ATO Duo is very easy to install on an aquarium or technical tank because everything is included in the box.
The Smart ATO Duo uses QST for real-time protection against any failure situation. QST can detect the malfunction of sensor, controller and empty reservoir to avoid pump dry running. The Smart ATO Duo triggers an audible and visual alarm when it detects that a refill time is 6 times longer than the first refill time.
For example, the first refill time was 10s. An alarm will sound if another refill time is more than 60s. take.
