The sand cone density test is an inexpensive method of determining in-place density of soils having maximum particle sizes up to 2in (51mm) using test hole volumes of approximately 0.1ft3 (2.8L).
The HM-100 Sand Cone Density Apparatus is a 1gal (3.8L) threaded plastic jar with detachable metal double cone fitting. The cone is threaded on one end, flanged to 6-1/2in (165mm) on the other, with a cylindrical valve of 1/2in (12.7mm) dia. orifice between ends. Valve has stops to prevent rotating past completely open or closed positions. Replacement plastic jar only is available as HM-102.
