Application:
Pendulum Charpy Impact Testing Machine is used to determine the impact toughness of metal materials
under dynamic load according to ISO148, ASTM E23 and EN 10045. It is suitable for laboratory, metallurgy
industry, machinery production, steel plant and other fields.
Liquid nitrogen refrigeration
JBDW-Y series Computer type: carry out the functions of zero clearing and automatic return, capturing the
value of lost impact energy and pendulum cycle by means of setting up with computer program, and the
results can be monitored, stored and printed out.
Low temperature system uses refrigeration compressor technology to achieve uniformity of the sample auto-cooling, with the use of heat balance principle and cycle mixing method.
JBDW-C series Computer type: carry out the functions of zero clearing and automatic return, capturing the
value of lost impact energy and pendulum cycle by means of setting up with computer program, and the
results can be monitored, stored and printed out.
