IEC 62368-1 Annex C
ISO 179 Charpy impact tester , ISO 180 Izod impact Tester
Product Introduction
Digital Charpy/Izod Impact Tester is used to test the impact
toughness of the non-metallic materials such as rigid plastic,
reinforced nylon, glass fiber reinforced plastic, ceramics, cast
stone, plastic appliance and insulation materials. It is widely
used in the scientific research institutes, universities and
chemical industry as the common quality test equipment.
Main Features
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
