Rika RK520-01 Soil Moisture & Temperature Sensor
PRODUCT DESCRIPTION
Rika 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 part adopts precision platinum resistance element, the product built-in drift calibration and temperature compensation circuit, can adapt to most applications.The soil moisture and temperature sensor can be permanently embedded underground and be connected to a data logger for unlimited testing.
