Capillary Flow Porometer

Model: iCFP-1100 / iCFP-1200 / iCFP-1500

  • iCFP is a new generation Porometer of Capillary Flow Porometer based on gas-liquid displacement method (ASTM-F316)
  • Non-destructive nature of testing
  • Fully automated & computer controlled operations
  • Testing of small samples as well as complete parts
  • Use of many non-wetting liquid (Example: Water, Alcohol, Silwet solution & Galwet solution)

According to ASTM F316-03

  • Where a nontoxic wetting liquid can spontaneously fill the pores in the sample and a non reacting Liquid can displace liquid from pores.
  • First the largest pores will get emptied, as they require lower pressure than smaller pores.
  • As the pressure is increased, more and more smaller pores are progressively emptied.
  • The pressure and flow rate of Liquid through the emptied pores provides the through pore distribution. The pressure at which through pores empty is inversely proportional to the pore size.
  • Through pores are the pores connected from one side of material to the other side. Innova Porometer measures the pore throat diameter, which is the most constricted part of the entire pore path.
