The MC311 EC controller with two pumps (MP810) provides fully automatic control of the EC nutrient solution in hydroponic and irrigation systems. It is specially designed to control the EC value in mixing tanks for fertilization. A small and precise flow rate through the peristaltic pump allows maintaining ideal EC values in the tank.
After selecting the desired EC setting from 0.8 to 2.8 mS, the controller measures the EC value of the solution and automatically adds fertilizer.
