The digital impact tester can measure the impact resistance of polymer materials. It calculates the absorbed impact energy based on the energy conversion relation. The precision of the impact hammer will highly affect the speed and mass position when impact, and this might influence the test accuracy.
QC-639S/T is equipped with 7" PLC touch screen. The machine encoder detects the angle for calculating the energy, and the built-in correction system compensates the loss causing by the friction of wind resistance. The optional dedicated software can support various analysis functions, record, generate reports, etc.
Izod and Charpy are the most common test methods. This machine can change the hammers and vises rapidly to satisfy different test methods and standards (ASTM & ISO).
