Overview
The Automatic Smoothness Tester is a high-precision laboratory instrument designed to measure the surface smoothness of paper and paperboard materials. Developed based on the Bekk smoothness testing principle, this intelligent device provides reliable and accurate data for evaluating the surface quality of paper products.
This instrument is widely used in papermaking plants, packaging industries, printing companies, research laboratories, and quality inspection departments. It helps manufacturers maintain consistent product quality by accurately determining the smoothness characteristics of paper surfaces.
Applications
The paper smoothness tester is suitable for testing a variety of thin materials, including:
Paper sheets
Paperboard and cardboard
Printing paper
Packaging paper materials
Other thin sheet materials used in industrial applications
It is an essential instrument for paper production quality control and laboratory testing.
Measurement Function
The Automatic Smoothness Tester is specifically designed to measure the smoothness value of paper surfaces. Smoothness testing helps evaluate how evenly a paper surface interacts with printing ink and coating materials.
Key measurement capability:
Accurate measurement of paper surface smoothness using the Bekk method
This test helps manufacturers improve printability, coating performance, and surface quality of paper products.
