Paper Stiffness Meter

The paper stiffness tester measures the resistance of paper to bending. The principle involves clamping one end of the sample and applying force to the other end to bend it to a specific angle, while a sensor records the moment value. It is used to evaluate paper hardness, packaging stiffness, and printability, and is commonly applied in quality control of paper products and material research and development.
Selection
When selecting, consider matching the measurement range to the sample thickness, ensuring accuracy meets testing standards, and ensuring fixtures are compatible with different paper types, with a simple operation interface. Pay attention to the convenience of instrument calibration and compatibility of data output formats. Determine whether to choose a manual or automatic model based on daily testing volume, and check the completeness of protective devices.
