Torque Tester

A torque tester evaluates the torsional resistance of materials by measuring the torque during rotation or twisting. It is used to detect the tightening or opening torque of products such as screws, bottle caps, and plastic parts, ensuring compliance with production standards.
Selection
When selecting a torque tester, it is important to consider that the measurement range should cover the torque of the samples, the accuracy should meet the testing requirements, the fixtures should be compatible with the sample shape, the data output function should facilitate recording, and the device dimensions should fit the workspace.
