Campbell Scientific CS650 Soil Water Content Reflectometer 30 cm

The Campbell Scientific CS650 Soil Water Content Reflectometer is a completely sealed sensor with two 30-cm-long stainless steel rods coming out of the epoxy body, where the circuit board is located. 

It measures propagation time, signal attenuation, and temperature. Dielectric permittivity, volumetric water content, and bulk electrical conductivity are then derived from these raw values.

We recommend using the Campbell Scientific CS650G tool inserting when installing this sensor.
