Diffusion Permeameter

· The diffusion permeameter can automatically analyze the diffusion properties and gas permeability of the sample.
· The diffusion permeameter can test samples with very low permeability, though it is difficult to measure with conventional methods.
· The diffusion permeameter is easy to use and does not compromise the permeability of the sample itself and can test a wide variety of samples at a wide range of temperatures and pressures.
 
Features
 · Based on the windows system, the software automatically controls the instrument, automatically measures and collects data and automatically generates reports; also can manually control the instrument.
· Compatible with Windows 95 and above.
· The test chart, test status and test results are displayed in real time.
· Non-destructive test.
· The whole test takes about 4 to 6 hours.
· Various samples and sizes can be measured.
· Multiple sample chambers can be provided.
· A wide range of gas, temperature and pressure tests.
· Hardly need to maintain.
 
Application
 The world's factories, from filtration to ceramics to the battery industry, use the diffusion permeameter for R & D and quality control, including films, filters, and battery electrodes.
Applicable industries: battery partitions, ceramics, chemicals, fuel cells, geotextiles, nonwovens, pharmaceuticals, powder metallurgy, textiles, filters / films, paper, castings and rubber industries.
