Stiffness refers to the ability of paper and cardboard to resist bending. The paper stiffness Tester is a special instrument for determining the stiffness of paper and cardboard.
1. Synchronous motor is adopted, with low noise and stable test
2. Adopt color large-screen touch LCD display to display various data in real time
3. The parameter setting is simple, and the test is convenient and reliable
4. Directly obtain the measurement results, including the mean, standard deviation and coefficient of variation
5. High degree of automation: data processing and action control can be carried out, and automatic reset and overload protection can be carried out
6. Data communication: The instrument is equipped with a standard serial RS232 interface, which can provide data communication for the upper computer integrated reporting system
7. It can measure the carton opening force and reverse folding force that reflect the folding and use effect
8. Measurable crease rebound force (crease stiffness)
