Proving Ring Penetrometer

Description

Used 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″ (19mm) dia.. shaft, graduated at 6″(152mm) intervals, and a cast-aluminum, two-hand-style handle.
