Handheld Proving Ring Pocket Penetrometer for Soil

The Proving Ring Penetrometer is a cone type of penetrometer which can be used in a number of applications. It serves as a rapid means for determining the penetration resistance of soils in shallow exploration work. The reading obtained in this method maybe correlated to standard or modified compaction data for compaction control in the field. Trafficability relationships can be obtained for quick field evaluation of sites. Correlation with the CBR or bearing capacity tests can be established by the user. In conjunction with the standard laboratory and field test, the H-4204 has proven to be an extremely useful tool for quick field checks and in reducing the possible number of the more time-consuming standard check tests. The instrument consists of a T-handle, one 36" penetration rod, one 18" extension rod graduated every 6", one proving ring of 220 lb. (99.79 kg) capacity with dial indicator and a removable cone point. The cone point has a base area of 0.983 square inch and a conical area of 1.938 square inch. The dial indicator furnished with this assembly has a maximum reading feature. A clutch type brake attachment maintains the reading until the brake is manually released.
