The sponge density tester adopts the Archimedes water displacement principle in accordance with ASTM D297?93, D792?00, D618 and D891. It is developed to measure relevant density values based on two main variables of materials and products. It takes the density of 1.000?g/cm? at 4℃ as the reference basis.
It adopts advanced microcomputer technology and high?precision sensing technology (electromagnetic balance type). It is widely used in medical research institutions, schools, enterprises and public institutions, highway construction, national defense departments and other fields, serving as an ideal device for high?speed and accurate measurement.
