The torque sensor of this testing machine is fixed on the top of the machine, and the sample to be tested is fixed at the lower place. The torsion test is carried out by rotating the lower clamp. This machine is equipped with a standard display to directly read the test data and can be set to perform torque tests and analyses under different speed conditions. The torque curve and the torsion direction are displayed in real-time during the test, and the torque value of the sample is fully recorded when the sample is rotated. The sample clamping method adopts a customized fixture, which is customized according to the sample size provided by the user.
