Electronic Smoothness & Porosity Tester (BendtsenType) For Determining The Smoothness And Porosity Of Paper And Board, Based On Mass Flow Meter Principle. Provided With Imported Sensor And Accessories.
Description/ Specification of Smoothness and Porosity Tester (Bendtsen Type) :
We are offering our customers a wide range of Smoothness and Porosity Tester (Bendtsen Type). The Roughness of paper or similar material is defined as the volume of air that is forced by a specified pressure difference escapes in unit time by passing between the surface of the specimen and flat metal ring resting on a specimen. The values indicate the surface smoothness of graded paper suitable for good print quality.
A sample is placed on a perfect plane glass plate, measuring head on the test piece and a controlled and low air in built pressure pass through a flat metal ring and the specimen.
The pressure difference read on the display.
Smoothness / Roughness Contact Pressure roughness - 98 kPa by measuring head of weight 267±0.5 gram
