The WSI-Corp Porometer 3G
The Porometer 3G is a third generation instrument for measuring the pore size of through-pores in sheet and solid materials. Typical samples include membrane filters, paper, porous plastics, thin films, and other sheet materials. It can analyze geotextiles, fabrics, woven and sintered metal sheet filters and many other porous materials.
Measures:
Wet and Dry Run Data, Click for Larger
  • Bubble Point or Maximum Pore Size
  • Mean (Flow) Pore Size,
  • Analysis Range 500µm to 0.05 µm diameter
  • Minimum Pore Size
  • Gas Permeability
  • Optional Liquid Permebility
TheWSI Porometer 3G uses the well known liquid expulsion technique in which one side of wetted porous sample is subjected to a continually increasing gas pressure. The pores empty of liquid when the applied pressure exceeds the 'capillary pressure'. The capillary pressure is dependent upon the pores size, the wetting liquid and its interface properties.
