Bendtsen Measurement Process

To perform Bendtsen Roughness measurements, the paper or cardboard sample is placed on a glass plate (supplied with the equipment), then the smoothness measurement head is carefully placed on the sample. After 4- 5 seconds the value can be read on the Touch Screen digital display

The Bendtsen Porosity measurement is measured as the air flow that passes through the sample through a surface of 10 cm2. To measure the porosity, the sample is placed in the test area of the porosity measurement head, Next press the button closing the jaws and in the same way as in the Smoothness, you can read the porosity on the touch screen digital display corresponding to the air flow that passes through the 10 cm2 of the sample.
