The Bendtsen Tester is able to measure both the roughness and porosity of paper and board. The instrument is easy to use. The 7-inch touchscreen uses intuitive icons. The original test design of Dr. Bendtsen had problems keeping the air pressure at a constant level. The 58-27 Bendtsen tester measures the air pressure in the head. Therefore, a change in pressure is directly recorded and controlled.
