The TDR200 will replace the TDR100 as the reflectometer for our time-domain reflectometry (TDR) system. TDR systems accurately monitor soil volumetric water content, soil bulk electrical conductivity, rock mass deformation, slope stability, or user-specific time-domain measurements.
Improvements over the TDR100 will include more robust electrostatic discharge (ESD) and surge protection, lower power usage (about half the TDR100’s power usage), and smaller size. The TDR200 will also have an LED that indicates when it is communicating and a USB port for connecting to a PC.
Several new settings for the TDR200 will enable better measurements in noisy environments. These settings include:
PC-TDR version 3 will be released with the TDR200. This software supports system configuration, troubleshooting, waveform display, and program generation. The new version will also contain a calibration wizard that helps you:
PC-TDR version 3 will be available, at no charge, from our website.
The TDR200 will be a drop-in replacement for the TDR100, allowing you to exchange the reflectometer without changing the datalogger, coaxial multiplexers, TDR probes, and programming. The many new features of the TDR200 and PC-TDR version 3 promise to benefit the many applications that use the TDR technology.
