Product description: QT-ML3 portable soil
moisture/temperature meter can be used for the
measurement of moisture of various types of soil and
media, and it can be used as a basic tool for on-site
observation or mobile measurement.
Principle
Using FDR (frequency domain reflectometry) principle,
the sensor emits electromagnetic wave with a certain
frequency, the waves transmit along the probe till they
reach the bottom of the probe and return to the sensor,
the output voltage is recorded. Because the dielectric
constant of the soil usually depends on the soil
moisture, the soil water content can be calculated
according to the relationship between the output
voltage and soil moisture.
