Description
The TDR-315N is MUNRO’s flagship Soil Smart TDR moisture sensor. It has a much higher amplitude waveform than our H-series sensors, which consumes more power but makes it very effective in taking accurate measurements in challenging soil environments. Being part of the Soil Smart Series means that its advanced waveform analysis works with all mineral soil types. 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 longer waveguides provide a very large sampling volume and high accuracy of the waveform propagation.
Its form factor is designed for shallower horizontal installations where it is pushed into the sidewall of a trench that has been dug to the desired measurement depth. A probe guide is provided to ensure that the waveguide rods are parallel when pushing them into the soil. It provides reading data through a 3-wire SDI-12 interface and is compatible with any data recorder that is compliant with SDI-12 version 1.4 and earlier.
