Time-Domain Reflectometry (TDR) Systems Soil water content, bulk electrical conductivity, rock mass deformation

About Time-Domain Reflectometry (TDR) Systems

Time-Domain Reflectometry (TDR) is widely used to measure soil water content, bulk electrical conductivity, and rock mass deformation. TDR systems based on a TDR100 are generally used for long-term projects and consist of a reflectometer, datalogger, coaxial multiplexer(s), cables, and probes.

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, th...read more
