Concrete Moisture Meter Work principle This instrument adopted the high frequency principle based on the introduction of the most advanced technologys. In other words,there is a fixed frequency inside the equipment. Once the moisture of the detected objects carried, the frequency through the sensor will be different. The deference between the frequencies will be displayed in figure after the conversion by current-frequency converter.
