XJ50D Digital Display Charpy and Izod Impact Testing Machine


XJ-50D digital display Charpy and Izod combined Impact testing Machine used to measure plastic, enhance nylon, glass fiber reinforced plastic, ceramic, and cast stone, plastic appliances, insulating materials and nonmetal material impact toughness. this tester can be used for research agencies, universities and colleges, nonmetallic material factory and other units or the inspection department for the laboratory experiment.

the machine adopts circular grating angle measuring technology, the digital measurement of material in a thrust in the process of absorbing energy and material impact strength, and have full energy loss detection and correction function. with high precision, good stability, large measurement range and other features, is a fully digital pendulum impact testing machine

It correspond these standards: ISO179, ISO180, GB/T1043, GB1834, JB/T8761, ASTM D256, ISO9854 and so on.
