Product Description
Product Description
Soil NPK sensor: The NPK sensor adopts FDR frequency domain reflection principle.
Based on the principle of electromagnetic pulse and the propagation frequency of electromagnetic wave in the medium, the apparent dielectric constant of soil is measured, so as to obtain the content of
soil nitrogen, phosphorus and potassium.
