The Balloon Density Apparatus is used for the determination of the in-situ density of well bonded soil according to NF specifications.
A metal cylinder is filled with water which is then pumped into a rubber membrane, mounted on the base of the cylinder, which take up the hole previously made in the soil pavement. The water pressure is controlled by a pressure gauge and the volume of the balloon is measured on the graduated piston stem.
Two versions available: 3000 and 6000 ml capacity. The apparatuses are supplied complete with base plate, 3 locking clamps and 6 reinforced membranes.
