■ Explanation

This machine is used to test various hard material specimens, and the energy absorbed by them after being hit by a certain angle and weight is used to determine the toughness of the material. After testing, this machine can automatically display angle, energy value, unit length energy value, and unit area energy value. The operation of this machine is controlled by buttons. After testing, the fixture is unscrewed to remove the broken test piece, and the operation is simple. This machine has an automatic memory function, which can display or print a single stroke, and can also print a single stroke of data.
