The 6050X1 TRASE System I is a self-contained, portable unit designed for field use for fast and accurate measurements of moisture in various materials (e.g. soil, cement, powders, grains etc) using Time Domain Reflectometry (TDR). This is a true TDR instrument with automatic beginning and end point determinations and full graphing abilities, allowing determination of both time and impedance differences along a waveguide. Measuring range 0 - 100% Volumetric Moisture content High Accuracy (+/- 2% FS or better), 1000 point resolution. Largest Pulse on any commercial TDR unit - 1.25V/ 120 ps.
