Computerized Torsion Testing Machine, Torsion Testing Machine is designed for conducting Torsion and Twisting on various metal wires, tubes, and sheet materials, torque measurement is done by a pendulum dynamometer system. Torque ranges can be adjusted by Auto Torque Selector. Torque can be applied to the specimen by geared motor through the gear box. Autographic recorder gives the relation between torque and angle of twist. The accuracy of torque indication is +1% of the true torque.
