The JBDW series microcomputer screen display automatic low temperature impact tester is used to measure the performance of metal materials against dynamic load impact at low temperature, so as to judge the properties of the material under dynamic load. This testing machine is a fully automatic control testing machine. The lifting, hanging, feeding, positioning, impact and temperature adjustments of the testing machine are all controlled by electrical, pneumatic and mechanical controls. It is easy to operate and has high work efficiency. It can be used after breaking the sample. The remaining energy automatically swings up and prepares for the next impact test.
1. Fully automatic, pendulum rising, impact, sample feeding, position, free releasing is realized automatically by easy PC mouse click;sample feeding, auto position the sample; high efficiency;
2. The impact of the blade with screw mounting
With two pendulums (big and small), PC software to display the energy loss, impact tenacity, rising angle, test average value etc. test data and result, also the curve display available; with calculation and report printing function. The dial scale can show test results too.
3. Safety pin guaranties the impact action, standard protection shell to avoid any accident.
4. Pendulum will automatically rising and ready for next impact action after specimen breakout.
