U.S. Army Corp of Engineers Sand Cone Density Apparatus

The sand cone density apparatus determines in-place density of gravel and coarse soils.  It features two identical cones with a large valve between them and a circular density plate for support on the bottom.  Its clear plastic cover on the top cone allows for viewing sand flow.  The unit also has handles for easier carrying.  The flange that fits the lower cone allows the apparatus to be used on holes up to 12″ in diameter.

Complies with U.S. Army Corps of Engineers specifications
