Adopting the principle of mixing fertilizer in a mixing tank, the fertilizer mixing precision is high, achieving a mixing precision of EC=±0.1 and PH=±0.1. It can output up to 20m³/h, suitable for large-area cultivation in connected greenhouses. It can mix 8 types of mother solutions simultaneously, manage 64 irrigation solenoid valves, and has 5 different irrigation management modes. It is equipped with EC sensors, PH sensors, irrigation water flow sensors, and independent fertilizer intake flow sensors for A+B+acid. It also features a 10-inch color touch display screen, can be connected to a
