Advanced Bendsten Permeability and Surface Roughness Tester
Description:
ā
Industries worldwide utilize permeability and surface roughness testers for R&D and quality control. Applicable industries include: Automotive, Battery, Biotechnology Separator ,Ceramic, Filtration, Fuel Cells, Geotextiles, Nonwovens, Paper, and Textiles.
Principle
ā
The Advanced Bendsten Air Permeability and Surface Roughness Tester is used to determine the permeability and surface roughness of porous solids. A gas such as air is forced to flow through the test sample. Measurements of the steady-state flow rate and the corresponding pressure drops provide the necessary data for calculation of the permeability using darcy and other units
ā
Optional Features :
• Permeability measurement of high flow rate samples
• Permeability of samples under compressive stress
• Use of elevated test temperatures and a wide variety of gases
Features
ā
• Windows-based software handles all control, measurement, data collection, and report generation; complete manual control also possible
• Comes with computer equipt with real-time graphical test display depicts testing status and results
• Non- destructive testing
• Length of test approximately 1 minute
• Wide range of acceptable sample types and sizes
• Multiple sample chambers available
• Minimal maintenance required
• Units in Darcy, Frazier, Gurley, and many others
• Completely automated air permeability tester
• Pneumatic Clamping
