Motorized Torsional /Twisting Testing Machine ISO 7800

Model: NJS-

NJS series Motorized Digital Torsion Testing Machine is mainly used to execute torsion test on various materials, measure torsion angles, angular stiffness and other content; record the testing data. Replace only with the appropriate clamps, it can complete the other component, bolts torsion test.

Motorized loading, high precision torque sensor to measure torque, photoelectric encoder to measure torsion angle, digital display test result, can measure torque under certain torsion angle, also measure the torsion angle under certain torque. After test automatically stop, automatic calculate material torsion strength, torsion speed consecutive adjustable; two directions torsion function. 

Motorized Torsional /Twisting Testing Machine conform with standard: ISO 7800
