Main Applications:

This kind of machine adopts the theory of electromagnetic excitation and specimen (spring) resonance. The system is kept in the best resonance condition automatically, and without any adjustment. The machine starts quickly with stable and reliable performances. It is very easy to operate and operators need not to be trained. The tester also has functions of digital display of vibration times and frequency, pre-set times, auto stop at break and auto store at break. The tester can carry on the spring testing either for one pairs or for multiple pairs at the same time.
