For determining powder or granulate density, bulk density factor and pourability of plastics materials. By means of this apparent density tester and a laboratory weight accurate to 0,1g it is possible to determine the apparent density i.e. the mass per unit of volume of loose material (powder or granulate) that can be poured from the funnel. Complies with ISO 60, ASTM D 1895 A, B & C, BS 2782 Method 621 A, and equivalent.
