RK520-01 Soil Moisture & Temperature Sensor to integrate the moisture and temperature measurement. The stainless steel probe is inserted into soil surface or soil profile to test soil moisture and temperature quickly. Moisture measurement part is designed on the basis of the principle of FDR, by measuring the dielectric constant of the soil in order to measure the volume of the soil moisture content, temperature adopts precision platinum resistance element, the product has built-in drift calibration and temperature compensation circuit, can adapt to most applications. The probe can be permanently embedded underground and be connected to a data logger for unlimited testing.
