Digital display material torsion testing machine is designed for conducting torsion and twist tests on various metal wires, tubes and steel materials. Torque measurement is by torque transducer while angle of twist is measured by photoelectrical coder.Torque range can be adjusted and torque is applied to specimen by servo motor and cycloid speed reducer. This tester is mainly applied in the research department, all kinds of institutions and industrial

and mining enterprises material experiment of various materials used for measuring the mechanical properties by torsion.
