Torsion Testing Machine is designed for conducting Torsion and Twist Tests on various metal wires, tubes and steel materials. Torque measurement is by Pendulum Dynamometer System. Torque ranges can be adjusted. Torque can be applied to specimen by geared motor through gear box. Autographic recorder can be provide to know the relation between torque and angle of twist on specific request. The accuracy of the torque indication + 1% of the true torque.
