Advantages

TDR (Time Domain Reflectrometry) technology delivers very accurate determination of soil moisture content. Data can be read from a handheld unit, logged or sent via a telemetry network to a PC for analysis. Our TDR technology is equivalently priced to good quality capacitance probes but is very much more accurate especially when used in “difficult” sediments such as heavy clays or those high in organic matter content. The soil moisture content is calculated inside the unit and the collected data can be read from the handheld unit.

Our TDR probes work by inserting the rods into the soil and within a few seconds the moisture measurement and soil EC values and temperature are presented on a display unit. The operating mode “Normal” shows you the value of Moisture, Temperature, and the RBC (material conductivity).
