GHL has been manufacturing dosing pumps for 25 years, and the latest iteration, the GHL Doser 2.2 is packed full of useful features. For a start, it is a standalone, app-controlled four-head doser capable of delivering as little as 0.1ml up to 150 times per day.
Its four 24-volt stepper motors are capable of dosing chemicals in the usual way but the dosing heads can also be used to supply top-off water, reactors or run continuously as part of an automatic water change regime.
It connects to the GHL Connect App or GHL Cloud Service via Wi-Fi, providing daily dosing data, notifications, alarms, and fully individual scheduling but it can also be a controller in its own right via two-level sensor ports, a temperature sensor port, and four stirrer connections to stir elements before dosing.
There are two versions of the Doser 2.2, the Smart Stand Alone unit (SA,) and then the Extension Dosers. Connect them together and the Stand Alone unit can control up to 16 pumps, or up to 32 pumps via the Profilux.
When you factor in its European brand name, four dosing heads, the breadth of its dosing capabilities, and the fact that you don’t have to buy into the full Profilux system to run it, it makes it one feature-rich complete dosing package.
