CS605

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 the probe's rods to the reflectometer). The CS605 consists of three pointed, large-diameter rods and a large epoxy head allowing installation in rugged environments.

The CS605 acts as a wave guide. Impedance along the rods varies with the dielectric permittivity of the surrounding soil. Because the dielectric permittivity of soil primarily depends on the amount of water present, soil volumetric water content can be inferred from the reflected measurements. Soil bulk electrical conductivity is determined from the attenuation of the applied pulse.

Campbell Scientific offers six TDR probes for our TDR100- and TDR200-based systems. The probes have different rods and connector cables allowing them to be used in different soil types and with different cable lengths. Other TDR probes available are the CS610, CS630, CS635, CS640, and CS645.
