High frequency capacitance moisture meter

To connect with the host measurement system using a long cable After the sensing frequency signal is collected, calculated, and processed by the host system and A/D converter, the moisture value is directly indicated by the digital display The host system is equipped with a temperature compensation circuit, which compensates for the impact of temperature on measurement accuracy by adjusting the parameters of the thermistor This instrument has the characteristics of fast speed, high resolution, ability to eliminate distributed capacitance and noise interference, wide range, good linearity, and wide application range
