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
