Smart ATO Lite is one of the most compact ATO in the world. Equipped with a tiny dual-optical sensor, it is easy to use for anyone and anywhere.
The unique QST (Quick Security Technology) can detect sensor or pump failure and avoid overfilling instantly without any complicated settings. With the LED indicator and the audible alarm, you can know its status at a glance.
The patented magnetic-mount dual sensor provides not only better protection but also easier installation. It can be set at any colors of the wall and work well in full dark.
The special design of the Smart ATO Duo controller can prevent the connector of the pump and the power adapter from rusted or damaged due to water and ensure users safety and longer product lifetime.
Smart ATO Duo comes with a bracket which allows you to fix the controller on the wall or the cabinet for neat wire arrangement.
Smart ATO Duo is a compact auto top off system for both nano and medium aquariums. Combined two precise sensors in one pack with a touch controller and integrated with QST (Quick Security Technology), which provides real-time protection against any failure and detects water empty, Smart ATO Duo offers you an easy, safe and efficient choice of auto top off systems.
