precisely monitors and controls fertilizer concentrations and pH for all types of greenhouse and field agricultural irrigation applications. Unlike flow-driven systems of the past, 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. The HANNA System is a bypass system which will not interfere with main line flow and thus does not impede line flow or pressure. This unit will accurately inject fertilizer in flow rates ranging from 5GPM to 300GPM.

HI 8000 Series Controller included with the system has 10 programs that allow the user to set various EC and pH values for a variety of plants. Each system allows the injection of a single fertilizer and 1 minors or (mild) acid. If preferred, each fertilizer injector can be set to a specific percent, allowing customized fertilizer mixtures from salts of the basic elements N-P-K, providing a considerable cost savings.

The HANNA Fertigation System also controls up to 8 irrigation valves (either sequentially or in groups of 2, 3, up to 8 at once) for complete automation of the fertigation process. Programs can be triggered by time, external switching, and/or flow, (e.g. spot watering - timer adjustable). HI 8000 is also capable of controlling an external agitator, handy for mixing fertilizer solutions. A backflow control allows the filtration system to be flushed and cleaned. Alarm controls and redundant monitoring help reduce error and unexpected events. This system can be synchronized with a GSM module which allows for remote monitoring and control from a PC. #32030
