Microflow Porometer - China

The PMI Microflow Porometer is a Capillary Flow Porometer with the ability to measure pore structure and permeability in nearly impermeable materials.

This instrument is user-friendly and fully automated.

The Microflow Porometer is an asset in quality control and R&D environments.

Operation Principle In this instrument a pressure transducer is located on the downstream side of the sample and the time rate of pressure change in the known volume of the down stream side of the sample chamber is used to compute very small flow rates.

The flow rate through dry samples is measured according to the differential pressure.

Under the increasing pressure, the gas flows into the back of the completely wetted samples in the chamber.

When the pressure increases enough to overcome the point where the capillary of the liquid works in the hole (maximum hole), that point is the bubbling point.

After confirming the bubbling point, increase the pressure and measure the flow until all the holes are empty and the sample is dry.

Application The microflow porometer is mainly used to determine the characteristics of low permeability membrane (gas separation membrane).

The instrument is suitable for packaging, rubber abd special gas manufacturing companies.
