About GHL Doser 2.1
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.
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.
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.
GHL Doser 2.1 Stand Alone:
The GHL Doser 2.1 Stand Alone has integrated control electronics and works on its own.
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).

Maintenance & Wear parts
Doser 2.1 pumps are largely maintenance-free. For optimal performance, we recommend occasionally cleaning and removing dust and other impurities from the inside of the pumps. The pumps must never be lubricated in any way!
Tubes, pumps and motors are wear parts, the life time depends on the use frequency, flow quantity and environmental conditions. When malfunctions (e.g. insufficient flow, losing prime, leakage, increased operation noise) or mechanical damages occur the wear parts must be replaced. Due to the maintenance-friendly design all wear parts can be replaced easily, all wear parts are available as accessories.
