Gurley Permeability Tester Vs. Frazier Permeability Tester: What`s The Difference?

 


The PMI Advanced Gurley Permeability Tester typically delivers an accurate and fast measurement of gas permeability of cylindrical, porous solid, and sheet samples. Not only just that, but this machine also features non-destructive and quick testing results. The PMI tester can be used for quality control and R&D.

The PMI completely automatic Gurley Permeability Testing device measures air permeability according to ISO 5636-3 and 5, TAPPI-T460 with pneumatic clamping and digital display.

On the other hand,

The PMI Advanced Frazier Permeability Tester smartly calculates fabric resistance of different textile materials, including woven, non-woven, and knitted to the passage of air-like parachute. Equivalent to Gurley Permeability Tester, this machine also provides an accurate and fast measurement of gas permeability of the solid, sheet samples, and cylindrical.

Frazier Permeability Tester also provides non-destructive testing and fast results; this tester is designed for R&D and quality control.

Mercury Porosimetry Testing Vs. Compression Porometer Testing: How Do the Two Differ?

Image
  In Mercury Porosimetry testing , the pressure is actually applied to force mercury into tinier and tinier pores. Hence, the pore size distribution can be projected by measuring the applied pressure and the intrusion volume in the test using Mercury Porosimeter. But what exactly is Mercury porosimeter? Precisely, it is an automated and versatile engineering instrument used to control various properties. It basically allows mercury porosimetry testing under higher or lower temperatures to put on concrete operational conditions. On the flip side, The Automated Compression Porometer is uniquely designed to portray the pore structure of any material under compression.
