ROUGHNESS AND AIR PERMEABILITY CODE: E.205.XXX
USAGE
To determine the roughness and the air permeability according to the Bendtsen method, Gurley porosity is calculated from the measured values.
DEVICE DESCRIPTION
The specially developed robust aluminum housing, which is equipped with a user-friendly touch screen, provides an excellent basis for the high-precision measuring mechanics of the Bendtsen. It consists of up to two pneumatic measuring cylinders with corresponding measuring heads, the control circuits and precise measuring sensors. To save the touch screen, the start button, which is separately attached 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.
