Stand Alone dosing pump unit with integrated controller, 4 Pumps, WLAN, USB, stepper motors and power supply, USB cable, 4x tube adapters.
The GHL Doser 2.2 Standalone has a flow rate of up to 45 ml/minute which make it ideal for standard dosing quantities and small volume ATO / AWC (less than 1.5 gallons daily recommended). Due to the precise 24 V stepper motors, micro-doses of 0.1 mL are also possible.
Robust mechanics and highly efficient stepper motors even allow continuous operation at a constant speed, e.g., for operating reactors. The Doser 2.2 SA provides the flexibility to daisy chain multiple GHL Dosing Units (EXT models: Doser 2.x / 2.x Maxi) to control up to 16 dosing pumps in total. The ProfiLux Aquatic Bus provides reliable and interference-free data transfer, even over long distances up to 100 m (300 ft.).
Dimensions: 8.66″ x 5.91″ x 3″ (without pumps)

Thanks to the high-quality technology inside the compact and modern GHL Doser 2.2, it provides precise and straightforward dosing and includes many more features. With the free GHL Connect 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). Operate the device comfortably from your smartphone or your PC. The connection is possible via Wi-Fi 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 2.2 is available as a Stand Alone Unit and an Extension Unit. The GHL Doser 2.2 Stand Alone has a controller and works independently.

PAB cables are not included and must be purchased.
One GHL Doser 2.2 SA can control additional GHL EXT Dosers (GHL Doser 2.2 EXT or GHL Doser 2.2 Maxi EXT) and can be extended to a dosing system with a total of 16 pumps.

Maintenance & Wear Parts
Doser 2.2 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.
GHL provides a 24-month limited warranty against all processing and material defects. Warranty period begins at the date of purchase.
