Specific Gravity is a fundamental measure of density used in a variety of industries. It refers to the weight of a given volume of a material in air at a standard temperature compared to the weight in air of an equal volume of distilled water at the same temperature.

To assess this property accurately, pycnometers prove to be highly effective. They are reliable instruments that can be used to test a wide range of materials, ranging from clay to gravel, but limited to those smaller than 10mm.

Pycnometers offer precision and accuracy in determining a material’s density, making them a valuable tool in the field of materials testing.
