Balloon Density Apparatus


TS-0990 (1600 ml) and TS-0992 (3000 ml) Balloon Density Apparatus are used for the on-site determination of the density of well bonded soil according to the ASTM and French standards respectively.

TS-0990 consists of a graduated cylinder, of 1596 ml capacity, housed inside an aluminium guard, with a reversible rubber aspirator pump, a 9 inches square density plate and 12 rubber balloons.
The principle of operation is similar to the sand replacement with the hole instead filled by a rubber balloon, to which water is pumped. The amount of water can be easily determined by the graduation of the cylinder.

The capacity of the TS-0992 apparatus is 3000 ml. The metal cylinder is filled with water, which is then pumped into a rubber membrane- mounted on the base of the cylinder. The water pressure is controlled by a pressure gauge and the volume of the balloon is measured on the graduated piston stem.
