GHL Doser 2.1

The GHL Doser 2.1 Stand Alone has integrated control electronics and works on its own. Its 24V stepper motors allow precise dosing even at the smallest flow rates (0.1 ml). The device is comfortably operated from your smartphone or your PC. The connection is possible via WiFi, LAN and USB.

Thanks to the high quality technology inside the compact and modern GHL Doser 2.1, it not only provides precise and simple dosing, but it also includes many more features. With the free GHL Contol App or the cloud service myGHL you can access your Doser from anywhere in the world to start dispensing programs or check the levels of your metering liquids.

The LED illuminated GHL Logo in the housing serves as a status indicator. It displays the condition of your aquarium by displaying various colors and tells you when something requires your attention.

The GHL Doser 2.1 is available as a Stand Alone Unit, as well as a Slave Unit. It includes two PAB-ports for connecting additional GHL Doser 2.1 Slave, Maxi Doser Slave or KH Director devices via ProfiLux Aquatic Bus.

PAB is an interference free CAN-Bus-System which allows for extremely secure data transfer between all PAB devices such as additional GHL Doser 2.1, KH Director, GHL Doser Maxi Slave devices. The range can be up to 100 m (300 FT). PAB cables are not included and must be purchased.

One GHL Doser 2.1 SA is able to control 3 additional GHL Slave Dosers (GHL Doser 2.1 Slave or GHL Doser Maxi Slave) and can thus be extended to a dosing system with a total of 16 pumps.
