The AMS Auto Drop Hammer is an option that can be added to your truck or trailer-mounted PowerProbe or any drill rig with an open, flat platform for geotechnical sampling. This auto drop hammer can be used to meet ASTM Method D 1586-99, a standard test method for penetration and split-barrel sampling of soils -- a method commonly known as SPT. The need no longer exists to have separate units for environmental sampling and geotechnical sampling. AMS Inc.
