The CS610 consists of three pointed, large-diameter rods and a large epoxy head allowing use in rugged environments. The probes act as a wave guide. Impedance along the rods varies with the dielectric constant of the surrounding soil. Because the dielectric constant 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.
The CS610 is usually used in applications requiring cable lengths longer than 15 m. A similar probe, the CS605, is typically used in applications requiring cable lengths shorter than 15 m. The CS610 and CS605 differ only in their cables.
