Cone Penetrometer, Direct-Read, 数字

使用d to determine the bearing capacity of sub-grades, or to measure soil compaction. It‘s light and easy-to-handle in the field, and provides a rapid means of determining the penetration resistance of soil in shallow exploration surveys. This penetrometer features a direct-read, digital gauge that is calibrated directly to a master load cell with an accuracy of 0.1 psi. This direct-read feature eliminates computations and charts to determine what the psi readings are. The penetrometer comes with a 30°, 1 in². (6.45 cm²) cone; a 37.25" x 0.75“(19毫米)直径.. shaft, graduated at 6"(152mm) intervals, and a cast-aluminum, two-hand-style handle.
