Principle of Plastic and rubber universal testers

Plastic and rubber universal testers adopt the principle of Archimedes buoyancy method and comply with ASTM D297-93, D792-00, D618, D891 and other international measurement standards, with the empty weight W1 and water weight W2 of the sample tested. The variables are used as benchmarks to convert the density/specific gravity value of the sample. The accuracy of the final measured value depends mainly on the two variables of the sample's empty weight W1 and water weight W2.
