Our torsion testing machines are designed and developed for conducting torsion and twist on various metal wires, tubes and sheet materials. The torque is measured by the pendulum dynamometer system. The torque can be adjusted by adding weight to the machine. Torque can also be applied to specimen by geared motor through gear box. Auto graphic recorder gives the relation between torque and Angle of twist. Our torsion testing machine offers accuracy indication of 1% of the torque.
