JBS series digital display pendulum impact testing machine are mainly used to determine the anti-impact capability of metal materials under dynamic load. They are the best testing equipments for many metal material manufactories, quality inspection departments and universities. The results will be displayed on both digital screen and dial gauge. JBS series impact testers can use pendulum’s residual impact energy to achieve the re-raising of pendulum, so as to save energy. The results can be printed out, be applicable for mass testing departments. JBS impact testers are strictly designed according to the standards ASTM E23, ISO148-1983 and GB/T3038-2002, GB/229-1994.
