GAS PERMEAMETERS

What is a Gas Permeameter?

A gas permeameter is a device used to measure the permeability of porous materials to the flow of gases. The basic principle of a gas permeameter involves applying a known pressure difference across a porous sample and measuring the resulting flow rate of gas through the sample. The permeability of the sample is then calculated using principles of fluid dynamics, such as Darcy's law, which relates flow rate, pressure difference, and material properties.

Our instruments are capable of steady-state, fall-off, pulse-decay, or combined permeability measurement methods.
