Specific Gravity Testing Machine is used to determine the density of a material compared to the density of water. The machine typically consists of a balance beam and a buoyancy chamber that holds the sample to be tested. The sample is first weighed in air, then submerged in water and weighed again. The difference between the two weights provides the information needed to calculate the specific gravity of the material. This type of testing is commonly used in industries such as construction, pharmaceuticals, and petroleum to ensure the quality of materials and products. Specific Gravity Testing Machine is available in various sizes and capacities to accommodate different types of samples.
