Bendtsen Roughness / Smoothness Tester

Bendtsen Roughness / Smoothness

A precision head with tightly controlled dimensions and weight is placed on the sample which in turn is on top of a ground glass plate. The amount of air leaked is measured by the flow tubes. Lower the flow rate the smoother the paper is.

Bendtsen Porosity (optional)

The sample is clamped between two precision faces one with a gasket, the air flow through the sample is measured by the flow tubes
