We are proud to offer a complete line of quality fertilizer injectors for sale in the United States.
All of these injectors continuously monitor the EC of the treated water as it is leaving the injector and adjust the amount of fertilizer being injected to exactly match the chosen set point. They are also able to monitor and adjust the pH of the water in the same way. Fertilizer stock solution(s) and optionally an acid or base solution are added to the mixing tank as needed through efficient vacuum/venturi systems, via solenoid valves controlled by the injector’s computer controller.
Models are available with maximum flow rates from 5 GPM to 200 GPM. Some of the models include an irrigation controller, and all can interface with any typical controller. Some models are designed to integrate directly with a climate computer such as Priva, or similar systems.
