Advanced Bendsten Permeability and Surface Roughness Tester
Description:
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
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
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
• 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
