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
