Soil Penetrometer (Needle Type)

Larger Image
The HS3251 penetrometer is used to perform moisture- penetration tests. In the penetration test a needle of given end area is pushed into a soil sample that has been compacted in a mold. The force is then directly read off the penetrometer scale by use of an internal calibrated spring. A moisture-penetration curve can then be plotted and used to indicate moisture and density in the field. The penetrometer is furnished with seven graduated needles of different surface areas. Approx. Ship Wt. 20 lb.
