Helium Pycnometer for True Density and Closed Porosity

真密度与闭孔率测定用氦比重瓶

Converting pore volume to porosity, or checking closed pores in ceramics, starts with true density. This helium pycnometer works by gas displacement with cells of 1, 10, 35, 100 or 135 cm³, giving ±0.03% volume accuracy and ±0.02% density repeatability. Each cycle takes 3–10 min. Use helium of 99.995% or higher purity.

Measurement principle
Gas displacement, Boyle's law
Sample cell volumes
1, 10, 35, 100, 135 cm³
Volume accuracy
±0.03% of reading
Density repeatability
