TDR-315N Sensor


A fully integrated digital TDR soil water content sensor (a.k.a., soil moisture sensor, probe, or meter) that has demonstrated superb accuracy consistently with excellent repeatability between six different soils including potter’s clay.  It is the first release of Acclima’s Soil Smart moisture sensors.  Allows for waveform capture.

The TDR-315N is a replacement to the former Acclima TDR-315L. 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 ultra-fast waveform generating and digitizing functions with a precision 5 pico-second 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 shallower horizontal installations where it is forced into the sidewall of a trench that has been dug to the desired measurement depth.
