Description
Roughness and air permeability
Code: E.205.xxx
Use
For determining roughness and air permeability using the Bendtsen method. The Gurley porosity values are calculated from the measured values.
Device description
The specially developed robust aluminum housing, which is equipped with a user-friendly touchscreen, provides an excellent basis for the high-precision measuring mechanism of the Bendtsen. This consists of up to two pneumatic measuring cylinders with corresponding measuring heads for measuring surface roughness and/or porosity, the control circuits and precise measuring sensors. To protect the touchscreen, the start button attached separately to the device can be used instead of the start button. The flow rate is 25-5000 ml/min. Other flow ranges are available on request.
