Kamoer Auto top up (ATO) One 2 for RO

The Kamoer ATO One 2 RO Edition tops up evaporated water straight from a reverse osmosis (RO) or RO/DI line. It does not need a reservoir bucket. A 12 V solenoid opens the line when the water level drops.

Key features

• 12 V solenoid valve plumbed into an existing RO/DI line
• Two optical sensors: the blue sensor starts a top-up, the red sensor stops the valve if the water rises too far
• Magnetic brackets to set the sensor height in a sump or rear chamber
• LED indicators and a buzzer if the overflow level is reached, or if the valve stays open for too long
• Automatic limit on how long the valve can run

Water and system compatibility

For marine and reef aquariums that already have an RO or RO/DI supply. It replaces water lost to evaporation so salinity stays steadier.

Setup

1. Mount the sensors on the magnetic bracket at the water line you want to hold.
