A compact automatic two-liquid fertilizer mixing device that can be installed in various locations, such as tank mounting or wall mounting! With simple operation, just set the EC value and press the ON button to automatically create nutrient solution at your desired EC value. It can be used by simply plugging it in and placing the EC sensor and tube into the tank. Additionally, it comes standard with a uniquely developed EC sensor that is resistant to dirt. By using the optional level sensor and solenoid valve, it automatically supplies raw water to the nutrient tank, eliminating concerns about dehydration in the nutrient tank.

We have achieved a reasonable price by packaging the minimum necessary systems for automatic liquid supply, including our independently developed inline EC control and sensors, liquid fertilizer mixing, liquid delivery and fertilizer pumps, and automatic control. Options for integration with solar radiation sensors, soil moisture sensors, etc., are also available.

Observation and display of CO2, temperature, and humidity. Automatic operation is possible in conjunction with each device.

The nutrient solution tank storage type is also compact! The automation of fertilization has been condensed into a compact form. Since it circulates and mixes within the nutrient solution tank, it allows for a consistently stable concentration of liquid supply.

Observation and display of solar radiation, temperature, and humidity. Each device can be linked for automatic operation.

By simply incorporating it into the discharge piping of the liquid supply system in the cultivation area, the EC value of the flowing nutrient solution can be measured and displayed inline. This is particularly useful for adjusting the injection amount using the dial on the injection pump or mixer while checking the actual EC value and viewing the display. Previously, the process involved using a portable EC meter to sample and measure the nutrient solution at the end of the irrigation tube, which was cumbersome. This system eliminates that hassle and maintains the desired nutrient concentration with high precision. It can also be used as an EC controller by connecting it to a quantitative injection pump.

• others

It observes and displays EC values and water temperature, automatically supplying liquid using two types of EC control methods (PID/ON-OFF control). It also transmits recorded data, which can be viewed and edited with a compatible app.

• others

Achieving advanced liquid supply control and scalability even in small facilities! It is equipped with EC management, solar radiation proportional control, moisture control, and system-specific injection control.

• others

It supports automatic irrigation linked to soil moisture levels with the injection of two liquids plus one liquid. By condensing the necessary functions into a compact design, we have achieved significant reductions in initial costs.

• others

The EC・pH control unit MEP-WPX2 is a control unit that adjusts EC and pH according to the settings, equipped with EC and pH controller sensors and injection pumps, all housed in a compact size. It automates the manual tasks of adjusting the EC and pH in nutrient solution tanks for hydroponics, enabling labor savings and stable nutrient solution creation.

• others

The "solar-powered automatic irrigation system" is a simple, power-free automatic irrigation device that can be installed indoors or outdoors. It is equipped with a storage battery, allowing for irrigation even in bad weather, and it can automatically irrigate based on soil moisture levels. Additionally, by using an optional automatic nutrient solution production device, it is possible to automatically mix one or two liquid fertilizers.

• others

The EC automatic adjustment automatic liquid feeding device MFS series is a highly controllable and stable automatic liquid feeding device that combines our core pump application technology with uniquely developed inline (injection) EC control technology.
