Digital Display Auto Torsion Testing Machine

Model : NJS Series 


  • NJS Series Digital Display Auto Torsion tester is designed and built for torsion test on metal & non-metallic materials, as well as parts & components. 
  • NJS is loaded through the rotation of the active cartridge driven by the AC servo motor and cyclonical pinwheel reducer motor. 
  • The torque and torsion angle are measured respectively by the high-precision torque transducer and photoelectric encoder. 
  • The digital torsion testing machine is an essential instrument to inspect torsion properties of materials for mechanical laboratories of aviation industry, construction industry, scientific research department, universities and industrial enterprises.


  • One key touch operation to finish the test automatically
  • LCD monitor to show the test in real time
  • Built-in Micro-printer to print out test results
