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.
54-BA460816 consists of a graduated cylinder of 1596 ml capacity housed inside an aluminium guard, a reversible rubber aspirator pump, a density plate 9 inches square, and 12 rubber balloons. The principle of operation is similar to the sand replacement but the hole is filled by a rubber balloon where water is pumped. The amount of water can be easily determined by the graduation of the cylinder.
According to NF standard, a 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.
NF Type Balloon Density Apparatus are supplied complete with complete with;
• Rubber balloons (membrane), 6 pcs./pack
• Base Plate
• Locking Clamps, 4 pcs.
54-BA460830 model Balloon Density Apparatus has a capacity of 3000 ml. A metal cylinder is filled with water and then pumped into a rubber membrane mounted at the bottom of the cylinder. Water pressure is controlled by a pressure gauge and the volume of the balloon is measured through the graduated piston body. Rubber balloons (membrane) must be ordered separately.
ASTM Type Balloon Density Apparatus is supplied complete with complete with;
• Graduated Cylinder. Heavy-duty plastic; dual graduated.
• Rubber balloons (membrane), Resilient latex.
