The Tunze RO Water Controller is an essential tool for maintaining a consistent water level in your reverse osmosis (RO) station's pure-water container. This automatic controller operates by detecting the water level and activating a valve or switch to add more water when necessary, ensuring that your system remains operational without manual intervention. It includes two sensors, a water valve, an 11 V power supply unit, and can be adapted with other components like a switched socket outlet for mains operation or used in combination to create a water changing system.
