The Paper Tube Compression Tester is a new-generation testing instrument developed by our company according to the latest national standards, specifically designed for measuring the compressive strength of paper tubes, edge protectors, cores, and other tubular or strip-shaped paper products. The instrument incorporates advanced components and a single-chip microcomputer for rational structural design. It offers a measuring range of 5~5000 N, resolution of 0.1 N, force accuracy within ±1%, and deformation error ≤±1 mm. The test speed is standard at 55±5 mm/min, adjustable from 0-120 mm/min, with return speed also adjustable within the same range. Platen parallelism is ≤1 mm, with unit switching between N/Lbf/kgf. It features an LCD display with curve graph visualization and a built-in modular thermal printer for direct printing of statistical results. Over-range protection and fault self-diagnosis functions are included. The structure is compact, lightweight, and easy to adjust. This instrument is a professional standard device for compressive strength testing and quality control in paper tube manufacturing enterprises, quality inspection agencies, and research institutions.
