The Cup Body Stiffness Tester is a new-generation precision testing instrument developed by our company according to the latest national standards, specifically designed for quantitative determination of the body stiffness of paper cups, paper bowls, and other paper containers. The instrument incorporates advanced components, supporting parts, and a single-chip microcomputer for rational structural design. It features a measuring range of 1-30 N, a resolution of 0.01 N, a test speed of 50±5 mm/min, and an adjustable probe gap of 40-120 mm. The instrument provides parameter testing, display, memory, and data processing functions as specified in the standard, and can directly print statistical results of all data. The loading method is automatic for easy operation. It also has over-range protection and fault self-diagnosis functions to ensure safe use. The overall structure is compact, lightweight, and easy to adjust with stable performance. This instrument is a professional standard device for cup body stiffness testing and quality control in paper cup manufacturing enterprises, quality inspection agencies, and research institutions.
