Applications :

NJS series is designed and built for torsion Test on metal & non-metal materials, as well as parts &

components. It is an essential instrument to inspect torsion properties of materials in mechanics laboratories

of aviation industry, construction industry, scientific research department, universities & industrial enterprises.

Features:

The testing machine adopts AC servo system & 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 with

high-precision torque transducer & photoelectric encoder.

l Automatic operation with only one key touch to finish the test;

l LCD monitors to show the test in real time.

l Micro-printer prints the test result.
