This kind of machine is used to determine the impact toughness of metal materials under dynamic load. The pendulum of the machine can be raised or released automatically. It is designed according to national standard GB/T3808-1995 "Charpy Impact Test Method for Metals" and ISO standard.

It can be also accordance with ASTM E23 standard as customer's special request. It has the features of easy operation, high efficiency, safe and reliable. The computer system can do data processing and get the test report. Under the super low temperature cooling system, it can check the impact performance of materials. The machine is especially suitable for laboratory, metallurgy industry, machinery production, steel plant and other fields.
