Specific Gravity

Specific Gravity is the ratio of the weight in air of a given volume of a material at a standard temperature to the weight in air of an equal volume of distilled water at the same stated temperature. The equipment mentioned below can be used to test a wide range of materials from clay to sand and gravel smaller than 10 mm.

SSO-1038
Pycnometer
IS: 2386 (Part 3)-1963
Consists of a 1 kg Glass Jar with Brass Cone, Locking Ring and Rubber Seal)
Sample Riffle Divider
IS: 1607-1977, 2720, ASTM C 136, D271, D421, D422, D423, D424, D427, D451, D452, D457, D806, BS: 812, 1377, AASHO T27, T87.
For the rapid collection of true representative samples from aggregates, sand and fillers, sample divider is required. Riffle Sample Divider consists of a metal box fitted with a series of chutes of equal width, which discharge the material alternatively in opposite directions into separate pans. The chutes of the riffle are steep enough to allow rapid flow of the material. Supplied complete with three containers.
