Proving Ring Penetrometer

Penetrometer, Proving Ring

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 Humboldt proving ring penetrometer 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.

All parts of the penetrometer are plated for resistance to corrosion and should be relatively maintenance free. The penetrometer needs little care beyond keeping the instrument free from dirt & rust, keeping all parts tight and frequently checking and if necessary re-zeroing the instrument.

Humboldt provides high quality penetrometer equipment and all the necessary components for accurate testing procedures.

Cone Penetrometer Digital Gauge with T-Handle – Designed to evaluate soil trafficability and manufactured to Corps of Engineers specifications. Now features a digital gauge that reads directly in psi.

Smart DCP for Dual-Mass Penetrometers – The SmartDCP makes collecting soil data with your Dynamic Cone Penetrometer much easier by automatically counting blows and eliminating the need for tape, pencils, paper and at times a second operator. It also provides vastly improved accuracy and ease of collecting and transferring data from the field to the office.

Dynamic Cone Penetrometer Test Set – DCP Test Set with sleeved drive hammer for safer operation.

Pocket Type Soil Penetrometer – For use by field personnel to check visual classification of soils. The hand penetrometer can be used to make quick estimates of unconfined compressive strength of cohesive soils.

Proctor Penetrometer Set – Used to establish the moisture-penetration resistance relations of fine-grained soils per ASTM D1558.
