The heart of our acid injection/pH control systems.
The Hanna Fertigation System continuously measures the actual EC and pH of the flow-through and precisely adjusts the concentration of fertilizer into the system.
Injecting multiple fertilizers to a specific conductivity results in an optimum nutrient application while advanced pH control improves nutrient absorption and plant health.
The unit will accurately inject fertilizer in varying flow rates ranging from 1 GPM to 350 GPM. Custom configuration is possible when higher flow rates are desired.
The HI8000 series controller has 10 programs that allow the user to set various EC and pH values for a variety of crops.
The system also controls up to 32 irrigation valves, either sequentially or in groups of 2, 3, or 4 at once. Programs can be triggered by time, external switching, or flow.
