Specific Gravity Balance provides a simple and quick mean to read directly the specific gravity of rubber and other elastomers, thus reducing labour and eliminating calculations. The time taken to find out the specific gravity of a sample is only about half a minute. The balance consists of an anodised scale with specific gravity (SG) printed on it standing vertically on a heavy base plate. A balancing arm is provided at the centre point of the scale. The arm is supported on two jewel bearings to minimise friction.

Sole Adhesion Tester consists of a cantilever type load cell with a digital readout to measure and indicate the force applied at the junction of the sole or heel and the upper and a set of interchangeable toe pieces having different curvatures. The load cell measures the force applied on the joint, which is indicated directly in kilograms on a digital readout with a peak force memory to indicate the maximum force applied before the failure of adhesion.

One of the methods for determining the abrasion resistance of elastomers is by a Rotating Drum Abrasion Tester. In this test the elastomer under test is abraded against an abrading surface mounted over a rotating drum. The abrading surface has a specified abrading power. The test specimen, which is in form of a button, is held against it under a fixed load. The abrading surface is made to rub against the test specimen by rotating the drum at a fixed speed, the test specimen being meanwhile made to move along the axis of the drum. The PROLIFIC Rotating Drum Abrasion Tester is designed to determine abrasion resistance index of natural and synthetic rubbers in accordance with the above principle. It consists of test specimen holder with a cylindrical opening adjustable between 15.5 and 16.3 mm to clamp the test specimen, with an arrangement to adjust the length of test specimen protruding out.
