technology index:

1. test accuracy : ±2%RH, the effective range for test humidity :5%∼99%RH



2. output relay touching point capacity : 220V 30A  resistance function can negative


carry



3. power voltage: AC220V 50HZ ,or AC380V (make by customer's requirement)
4. work conditions :0∼50°C, relative humidity ≤85%,have no corrosive and


strong electromagnetic radiation's occasions.



    install and use 

After install the meter according to the regular ,install the humidity sensor at


need test humidity's occasion , the three go-between of sensor ,the blue is+5V wire


(green pipe ) ,the brown is signal wire (red pipe ), yellow and blue double


color are land wire (green pipe ) distinguish link with the meter's  "+5V, SIN,


OV", when the go-between isn't long enough ,can use the relative normal three sensor


wire to add up , but can't exceed 10 meters.Link wire's base ( three phase


design )
