Density Drive Sampler
The density drive sampler determines in-place density of soil. It drives a thin-walled tube into the soil mass to obtain a relatively undisturbed sample. The sampler verifies compacted fill placement or obtains samples from the bottom of shallow excavations. Its zinc-plated, steel drive head and sliding weight hammer work with separately ordered drive tubes. The 10lb drive head features shock and reducing spring to guard against fatigue failure.
