The TDR 100 is 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. Choose either the 7.5cm,12cm or 20cm (3in, 4.8in, or 8 in) probe rods to suit your measurement depth. The LCD interface provides two modes: volumetric water content and relative water content (irrigation management) mode.
Hand-held design allows for easy transporation and storage. Units connected by 5ft. Cable. Measures in less than one second.
