Schopper-Type Paper Folding Endurance Tester NZD-1

Product Name: Schopper-Type Paper Folding Endurance Tester

Product Model: NZD-1

Basic Application Scope: This instrument is suitable for determining the folding endurance of paper with a tensile strength greater than 1.33 kN/m and a thickness less than 0.25 mm. The structural parameters and technical performance of the instrument comply with the requirements of QB/T457-2002 "Test Method for Paper Folding Endurance" and other relevant standards.

Product Features: The instrument uses photoelectric control technology to automatically return the folding clamp to its original position after each test, facilitating the next operation. It has powerful data processing capabilities: it can statistically analyze experimental data from multiple samples in the same group, including maximum value, minimum value, average value, and coefficient of variation. These data are stored in the microcomputer and can be displayed via digital tubes. Additionally, the instrument is equipped with a printing function.
