About 6 months old looks & works as new.

Also has a 10L container that goes with it if wanted.

(1) The precise water level is ensured by a non-wearing optical sensor and a transistor switch without any moving parts. This sensor is insensitive to soiling, light or magnetic fields.

Its “automatic eye” recognises the water level precisely, even small waves or level variations cannot irritate the unit.

(2) An independent safety sensor with a separate power supply circuit and relay control ensures reliable overflow protection.

(3) An electronic time controller and current limiter for the pump connected result in a higher operational safety. This unit protects the metering pump against running dry and reports an empty storage container.

(4) All functions are clearly displayed by LEDs; safety messages are also indicated by acoustic signals.

(5) The osmotic regulators are all operated at safety extra-low voltage.
