The TDR 100 Soil Moisture Meter measurement principle is based on Time Domain Reflectometry (TDR) and is considered one of the most accurate approaches to measuring soil moisture. The TDR 100 will be highly accurate across all soil types where EC is less than 2mS/cm.

Soil Volumetric Water Content

The TDR 100 operates off 4 x AAA batteries that have a life of approximately 12 months.

Select from the 3.8cm, 7.5cm, 12cm or 20cm probe rods (sold separately) to suit your measurement depth. The LCD interface provides two modes: volumetric water content and relative water content (irrigation management) mode. For data logging and GPS capabilities, see the TDR-300 Soil Moisture Meter.
