PSM 165 Pore Size Distribution Analysis - Capillary Flow Porometer / Pore Size Analyzer

PSM 165
Pore Size Distribution Analysis - Capillary Flow Porometer / Pore Size Analyzer

The Capillary Flow Porometer PSM 165 provides a means of mercury free and non-destructive characterising of porous materials with regard to their pore size distribution (membranes, ceramics, nonwovens, sinter metals, ...) on basis of ASTM D6767, ASTM F316-03, ISO 2942, ISO 4003. The test is conveniently supported by a PC with user-friendly control software PSMWin. Amongst others the following three main parameters describing the inner structure of the material can be obtained with this compact pore size analyzer.

Bubble Point (largest pore diameter)

Pressure drop at which the wetted sample is starting to become gas permeable.

Pore Size Distribution

Permeability weighted pore diameter distribution calculated from wet flow curve (pressure drop vs. volumetric flow rate of the wet sample) and dry flow curve (similar to wet flow, but obtained on a dry sample).

Mean Flow Pore Size

Pore diameter corresponding to the pressure drop where the wet flow value is half (50%) of the dry flow.

  • Generation of Nondestructive, structural characterisation of filter media with non-mercury porometric measurement technique
  • Quick and easy sample change
  • Several sample holder dimensions for optimal fit to different sample sizes
  • Computer controlled test procedure and user friendly data acquisition and presentation in Windows environment
  • Compact instrument
  • User defined fluid possible
  • Calibration of particle measuring instruments
  • Aerosol research
  • Filter testing
  • Determination of separation efficiencies
  • Inhalation and toxicology studies
  • Generation of tracer particles

The user-friendly analysis and control software PSMWin was especially developed for Capillary Flow Pore Size Meter PSM 165. By means of the software that works on Windows computers three main parameters can be determined that describe the material structure.

  • Pore size distribution of porous media
  • Bubble point
  • Mean flow pore size

Data acquisition and processing are fully computerised and specific instructions on tasks such as inserting the filter sample are given to the operator. This ensures that errors arising from incorrect instrument operation are reduced to a minimum. The logged data can be displayed graphically or in tabulated form.
