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.
The CS605 is used in TDR100 and TDR200-based systems. This probe is recommended for typical soils (soil bulk conductivity ≤1.5 dS/m) and cable lengths of less than 15 m (measured from the tips of t...read more
The CS610 is used in TDR100 and TDR200-based systems, and it is recommended for typical soils (soil bulk conductivity ≤1.5 dS/m). Its RG8 cable allows the CS610 to have cable lengths longer than 15...read more
The CS630 is used in TDR100 and TDR200-based systems. This probe consists of a Santoprene head, three pointed rods, and a standard RG58 cable. The length of each rod is 15 centimetres, allowing the pr...read more
The CS635 is used in TDR100 and TDR200-based systems. This probe consists of a Santoprene head, three pointed rods, and a low-loss LMR200DB cable. The length of each rod is 15 centimetres, allowing th...read more
The CS640 is used in TDR100 and TDR200-based systems. This probe consists of a Santoprene head, three pointed rods, and a standard RG58 cable. The length of each rod is 7.5 centimetres, allowing the p...read more
The CS645 is used in TDR100 and TDR200-based systems. This probe consists of a Santoprene head, three pointed rods, and a low-loss LMR200DB cable. The length of each rod is 7.5 centimetres, allowing t...read more
This tool aids insertion of a CS605 or CS610 TDR probe in high density or rocky soils. The CS605G has rods of similar diameter and the same spacing as the CS605 and CS610. The tool can be driven into...read more
Soil moisture sensors (sometimes referred to as volumetric water content sensors) measure the water content of soil. These sensors can be used to estimate the amount of stored water in a profile or ho...read more
