Product Serial : QC-639R (U)
Computerized Impact Tester
Confirm to ISO13802、 DIN53453、ASTM D256、 ISO180 、ASTM D6110 、ISO179 Standard
Computerized impact tester can be used to determine impact resistance of polymers. It use the energy conversion to calculate the energy absorbed by the sample after impact. The precise of impact hammer will highly affect the center position of its mass and impact speed, which in turn influence the test accuracy. QC-639R/U can lift and release the impact hammer automatically for better test efficiency and operator safety. It is equipped with 7" touch screen. It uses encoder to detect the angle for calculating the energy and has built-in correction system for the loss causing by the friction of wind resistance. For increase the test precise, there is an optional dedicated software to analyze, record and generate report and so on. Izod/Charpy is the most common methods. QC-639R/U can support to change the impact hammer and vise rapidly to satisfy different test condition and standards (ASTM & ISO).
