Principle: 
According to the standards of GB/T533-A, GB/T1033.1, GB/T6155, GB/T23561, YB/T5300, JB/T7984.3, GB/T 1713,  GB/T8929, GB/T1713, GB/T208, GB/T5071, QB/T1010, GB/T9966, GB/T18856, GB/T24203, GB/T8330, SL-237, and by adopting the immersed volume displacement method of Archimedean principle, and cooperated with pycnometer, it can show the measuring result directly.

Notices:
■ Under the immersed method, choosing the liquid which can not dissolve but can moisture the sample surface is important.
■ For ceramic materials, such as feldspar, quartz, and ceramic products, distilled water can be used as the liquid medium.
■ For cement material, kerosene, xylene, or other organic liquid can be used as the testing medium.
■ For inorganic powder, organic liquid also can be chosen. 
■ By using porcelain mortar to rub powder and filter it by 240 mesh sieve, then put the powder in the weighing bottle, and dry it by moisture meter under 105℃, take out and cool it to room temperature in desiccator.
