Advantages

New function list

・ This product is equipped with a function to prevent overinjection.
・ Setting of one cycle operation time is possible, and when excessive injection occurs, notification is made by E display and buzzer sound.
・ The instrument uses a free power supply.
・ Transmission output DC 4 to 20 mA for EC, pH, and temperature is standard equipment. 
・ LCDs are brighter and easier to see.
 
・ Compact design combining a pH meter with an EC meter and a dual dispense pump.
・ Complex wiring has already been connected. Only inserting an outlet can be used. 
Only inserting an outlet can be used. Measurement control is possible.
・ Connect the piping to the fertilizer tank and dilution tank with a simple hose.
・ Since an anti-siphon valve is provided, the tank can be installed freely regardless of the position of the tank above and below the ground.
・ Diaphragm-type metering pumps are used, which are resistant to dust and are less susceptible to failure.
・ Prevent EC overconcentration by the interlocking function of the circulating pump and the metering pump.
・ The power supply can select 100V or 200V single phase.
・ Optionally, the acid/alkali pump can be set to control three points: fertilizer, acid, and alkali.
Some unit types are available.
