Stiffness is an indicator to measure the flexural strength of paper. Paper Stiffness Tester is a dedicated instrument to measure the stiffness of paper. 

This Paper Stiffness Tester uses a highly precise miniature sensor. After being upgraded, the test stability, accuracy, and sensitivity of the product are greatly improved. Thus it is suitable for testing the bending stiffness of low quantitative paper.

Paper Stiffness Tester Overview

Stiffness is an indicator to measure the flexural strength of paper. Paper Stiffness Tester is a dedicated instrument to measure the stiffness of paper. This product is designed based on the principle of static bending, conforming to the requirement of ISO 5628:1990—Paper and board -- Determination of bending stiffness by static methods -- General principles.

Paper Stiffness Tester

This instrument uses a highly precise miniature sensor. After being upgraded, the test stability, accuracy, and sensitivity of the product are greatly improved. Thus it is suitable for testing the bending stiffness of low quantitative paper.

Paper Stiffness Tester Features:

  • The instrument uses single-chip microprocessor controlling technology, configured with aluminum panels, standard buttons are sensitive and durable;
  • Liquid crystal display, with test data memory function;
  • High-speed thermal printer output;
  • Automatic completion of the test and the probe resets automatically;
  • With test data statistical processing functions.

This product is designed based on the principle of static bending, which is: to bend a free end that is clamping the test sample when the sample is bent to a certain angle, the resistance is the bending stiffness (the unit is mN), or to record the arithmetic product of the resistance and the length of the test sample (the unit is mN.m).
