TDR-305N Sensor


Completely integrated TDR soil water content sensor (a.k.a., soil moisture sensor, probe, or meter) accurately yields VWC and BEC/PWEC with a high-speed 300 pico-second rise time for a detailed wave form analysis. Designed for high EC tolerance when taking readings. A great measurement solution for soils with exceedingly high salt levels.

The TDR-305N is a modified version of the TDR-310N. The very short waveguide allows this sensor to make very shallow measurements and to be used in higher conductivity environments with a sacrifice in total measurement volume. It has a high voltage waveform output, which makes it effective in taking measurements when the soil electrical conductivity is high. It also consumes more power than the TDR-315H. It is a complete integrated time domain reflectometer that combines ultrafast waveform generating and digitizing functions with a precision 5 picosecond resolution time base and highly sophisticated waveform digitizing and analyzing firmware that provides true time domain analysis of soil-propagated waveforms. Its form factor is designed for easy vertical installation in an augured hole using a 34 mm flat-bottomed auger.
