Main Features:

1. High measuring accuracy, high response speed, good interchangeability.
2. Embedded microprocessor, read volumetric water content of soil directly.
3. Digital signal output，MODBUS communication protocol，continuous measurement.
4. Calibration formula configured in the sensor，no need to recalibrate when change the RTU or portable box.
5. Suitable for different soil conditions, meet the measuring accuracy standard 2% after calibrating.
6. Stainless steel materials，hermetically sealed structure, can be used in any geological environment.

7. Conforms to Soil Moisture Content Monitoring System General Technical Requirements staged by Ministry of Water Resources.
 8. Can be wildly applied in soil moisture monitoring, water-saving irrigation, greenhouse controlling, precision agriculture and meteorology, etc.
