Product Serial : QC-639S、QC-639T
Digital Impact Tester
Confirm to ASTM D256、ASTM D6110、ISO179、ISO180、ISO13802 Standard

Small capacity pendulum type impact testing equipment, it is usually be used in high polymer material impact strength test, use potential energy of pendulum to impact specimen, analyze the remaining potential energy after impact to calculate specimen absorbed energy during test.

It has big correlation between pendulum mass, length, rigidity and so on accuracy and test precision, especially pendulum mass center position will affect impact speed and produce test error. This type impact tester is provided with digital display to show angle, energy, other functions and in-build wind resistance, frictional loss automatic calculated formula, users can easily and convenient to use.

IZOD / CHARPY are two types of common tests; QC-639S/T can be carried out test in different test methods by replacing pendulum and vise type. Machine is fitted simple specimen collection area that provide user safer test environment.
