Dynamic Cone Penetrometer

If you cannot find the part number in the documentation please provide detail. Specific to this item, it could include part number or application detail, (ex. 20 meters of cable, or 20 litres of volume)

The most widely accepted, portable method for evaluating strength and density of soil, in situ.

The dynamic cone penetrometer uses a 6.8 kg drive mass falling 50.8 cm that strikes the anvil to cause penetration of 3.8 cm diameter cone (45 degree vertex angle) that has been seated in the bottom of a pre-augered hole. The blows required to drive the embedded cone a depth of 1 3/4" have been correlated by others to N values derived from the Standard Penetration Test (SPT). Experience has shown effectiveness in pre-augered holes to depths of 4.6 to 6.1 cm. The cone can be replaced with a plated drive tube assemble for collection of 7.6 x 25.4 cm samples in pre-augured holes.

Includes: DCP sleeved drive hammer, 45 degree vertex angle cone with a 3.8 cm diameter cone, extensions, laminated instruction sheet, ASTM STP 339 Special Publication.

Material: heat-treated cone, zinc-plated components
