Description

The PMI Diffusion Permeameter provides fully automated analysis of diffusion and gas permeability. PMI's Diffusion Permeameter tests materials that typically have very low permeability and are therefore difficult to measure by conventional means. The user-friendly PMI Diffusion Permeameter features nondestructive testing and can test a wide variety of samples and gases over a wide range of temperatures and pressures.

Principles of Operation

Industries worldwide utilize the PMI Diffusion Permeameter for R&D and quality control. Samples tested include membranes, filters, and battery electrodes.

Applicable industries are:

See our paper Characterization of Water Vapor Permeable Membranes.

For more information about applications please see our technical papers.
