1. Testing medium should be uniform.
2. In measuring the water content in surface soil, the sensor must be inserted vertically. Do not bend the sensor when it is inserted, otherwise it will be damaged.
3. In multi-layer soil water content measurement, the sensor should be buried in the soil and parallel to the ground. Make sure the probe is not blended.
4. When removing sensors from the soil, please hold the sensor housing shell and do not forcibly pull on the cable. Soil on probes should be brushed off thoroughly.
5. Please keep the sensor in dry & clean conditions.
