Advantages
・Large LCD indication with backlight. |
・Provided with the scaling functions of DC4 - 20mA in transmission output, connection can be made to a wide range of external equipment. |
・Provided with ON/OFF control and twin timer control, the meter is fit for control in various places. |
・With a built-in 24-hour timer. Irrespective of the conductivity, ON time and OFF time settings and control of the number of times can be made, thereby capable of being utilized in various applications. |
・Having a built-in zone alarm interconnected with conductivity, an out-of-range alarm is output as an output at one point. |
・The meter has 2 ranges of conductivity measurement: 2000μS/cm and 20.00mS/cm, and a switching between /cm and /m can also be made. |
・As for the electrode, the alternating current 5-electrode method is employed that is resistant to dirt and involves little measurement error. |
・Titanium is used for the detection electrode, and PVC is used as the body material, thus having excellent corrosion resistance. |
・The power supply is designed to work at any voltage between AC100 and 240V. |
・The outline is compact, with the dimensions of 96W×96H×145D. (DIN96) |
Applications
・Nutrient solution control in a plant factory. |
・Nutrient solution measurement and control in hydroponics (a hydroponic greenhouse). |
・Replenishing water control for a cooling tower. |
