TDR Probes and Installation Tools
Probes for soil volumetric water content and soil bulk electrical conductivity

About TDR Probes and Installation Tools
Impedance along the rods of TDR probes varies with the dielectric permittivity of the surrounding soil. Because the dielectric permittivity of soil primarily depends on the amount of water present, the soil volumetric water content can be inferred from the reflected measurements.
