A. High-precision intelligent controller equipped with LCD display which you can read the data intuitively and accurately; B. China's first carbon fiber lever (It has been patented); it succeeds in doing experiments without shaking involving the impact direction, improving the rigidity of materials, and concentrating impacting strength on the centroid of the pendulum, and using life increases. C. Imported high-resolution digital encoders, higher and more stable angle measurement accuracy; D. Aerodynamic impact hammer and imported ball bearings greatly reduce mechanical friction losses E.Automatic calculation of the final result, 12 sets of the test data can be stored and averaged; F. Optional interface of Chinese and English; units ( J / m, KJ / m2, kg-cm / cm, ft-ib / in )can be customized according to customers’ requirements. G. Built-in mini printer to print the test data
