TDR-300 Soil moisture sensor

When precision irrigation decisions count, the FieldScout TDR Soil Moisture Meter Series offers growers a tool to eliminate the guesswork. Based on proven time-domain measurement technology, these portable units accurately measure soil moisture across the full range of soil moisture conditions.
The LCD display shows results in two modes: % volumetric water content or relative water content.
The calculation is performed by programming (calibration) of the unit to a high (water-saturated soil) and low (wilting point) volumetric water content of the soil. These points can be programmed variably, depending on the location and soil type.
