Description

The 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 anodized scale with specific gravity (SG) printed on it standing vertically on a heavy base plate. A balancing arm is provided at the center point of the scale. The arm is supported on two jewel bearings to minimize friction.

Two stainless steel pins are suspended from one end of the arm. One of the pins is attached through a short length of yarn and the other through a long length of yarn. The second pin is kept immersed in water inside a tall transparent jar kept on the base. This pin also acts as the sinker.
