CS625

Water Content Reflectometer for CR200-series

The CS625 is a water content reflectometer designed specifically for the CR200-series data loggers. Volumetric water content measurements are made using time-domain methods that are sensitive to dielectric permittivity. The CS625 has a 0 to 3.3 V square wave frequency output.

The CS625 consists of two 30-cm long stainless steel rods connected to a printed circuit board. The probe rods can be inserted from the surface or the probe can be buried at any orientation to the surface, depending on your requirements.
