Model TDR315H - Soil Moisture Sensor - Technical Performance Datasheet

The TDR315H is a true Time Domain Reflectometer designed to provide highly accurate Volumetric Water Content Measurements in soils and other porous media. It incorporates the same basic TDR components found in console-based TDR instruments costing 20 times more – housed inside the small enclosure that also supports the 15 cm waveguide. The patented TDR function is coupled directly to the waveguide, thus eliminating the coax cable associated with conventional TDR devices. The absence of the coax cable provides the TDR315H with higher bandwidth waveform data thus improving its resolution and sensitivity over expensive conventional TDRs.
