Soil moisture

This the ideal tool for quick, reliable, and convenient measurement. Whether you're in a field, greenhouse, or laboratory, the TDR 100 will provide the results you want. Based on the proven time-domain measurement technology, the portable TDR 100 accurately measures soil moisture across the full range of soil moisture conditions.

Select from the 12 cm or 20 cm probe rods to suit your measurement depth. The LCD interface provides two modes: volumetric water content and relative water content (irrigation management) mode. Wet and dry volumetric water content set points can be programmed into the logger for 5 different locations or soil types.

Default values for 5 common mineral soils (using permanent wilting point and field capacity as the set points) are set at the factory with new meters. Hand-held design allows for easy transporation and storage. Units connected by 5ft. cable. Measures in less than one second. A comprehensive and clearly understandable manual is supplied with the instrument.

Measuring rods are to be ordered separately.
