Relative moisture sensor TDR 100

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. Key Advantage - Usable in the field, greenhouse and laboratory - Simple and reliable Specifications Resolution 1.0% Accuracy ±3.0% volumetric water content with electrical conductivity <2 dS m –1 and clay content < 30% Range 0% to saturation (Saturation is typically around 50% volumetric water) Power 4 AAA alkaline batteries Approximately 12 month life Display 16 character, 2 line LCD Weight 1.5 lbs.
