Product name: Impact testing machine
Product model: JB-300B
Product function: Used to test the impact resistance of metal materials under dynamic load in Charpy impact test (V-type and U-type notch specimens).
Based on standards:
GB/T 3808 Inspection of pendulum impact testing machine
JG 145 Pendulum impact testing machine》
GB/T 229 Charpy notch impact test method for metals
Semi-automatic control, the control button can realize the automatic swing, automatic hanging and automatic impact of the pendulum.
Continuous impact test and batch impact test are fast, accurate and efficient.
