DCP Test Set without Auger Set (H-4202AX)
The H-4202X DCP Test Set without an auger set. The H-4202 set includes; (1) standard hammer assembly (H-4202.1), (1) heat-treated 45° cone penetrometer point with a 1 ft. adapter rod (H-4202.3), (4) 2.5 ft. E drill rod extensions (H-4202.225). The Dynamic Cone Penetrometer (DCP), originally developed by George Sowers, uses a 15 lb steel mass falling 20 in. to strike an anvil to penetrate a 1.5 in. diameter 45° (vertex angle) cone that has been seated in the bottom of a hand-augered hole. The DCP can be used effectively in augered holes in nearly all types of soils to depths of 15 to 20 ft. (4.6 to 6.1m). Components are zinc-plated and cones are heat-treated. The cone can be replaced with Drive Tube Assembly (H-4202.7A).
