CS - 615 Soil Moisture Probe
CS-615 Soil Moisture Probe

The Campbell Scientific CS-615 utilizes time domain reflectometry (TDR) to measure the volumetric water content of a soil. It measures the propagation velocty of an electromagnetic pulse through the soil which is converted to the soil moisture content using a callibration equation.

The CS-615 soil moisture probe has been succeeded by the CS-616 soil moisture probe.
