VI. Working Principle

The test is based on the volume displacement method. A liquid medium is first added into the Le Chatelier Flask, and the initial volume is recorded. After adding the powdered sample, the displaced liquid volume is measured. The relative density of the material is calculated according to the mass and volume difference of the sample.
