Soil Moisture Sensor (TDR-310H)

TDR-310H

The TDR-310H is one of MUNRO’s H-series sensors, which are very low power and suited perfectly for power-conscious applications. Being part of the Soil Smart Series means that it’s 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 form factor is designed for easy vertical installation in an augered hole using a 34 mm flat-bottomed auger. It mates with a 1” schedule 40 PVC pipe that acts as a handle in its installation to any desired depth. It provides reading data through a 3-wire SDI-12 interface & is compatible with any data recorder that is compliant with SDI-12 version 1.4 and earlier.
