HIT-2494 Pendulum Impact Tester

High performance Charpy/Izod Impact Teser is a high performance impact tester designed to precisely determine the absorbed impact energy and resistance to breakage of plastic specimens.

  • The innovative design allows this tester to be used for both Izod and Charpy test.
  • Unique and innovative design: vice and pendulum allows operator to run alternatively Charpy and Izod tests without changing the instrument geometry.
  • Impact speeds of 3.8m/s & 3.5m/s as well as multiple impact energies can be generated by one pendulum.
  • High mass, traditional pendulum design concentrates energy at the impact point with minimal energy loss due to vibration.
  • The electrics contain a high-resolution encoder for accurate measurement of the impact angel.
  • Touch screen control for quick and easy input of parameters, interactive software allows for users input regarding complete, partial hinge broken and non-broken samples.
  • Tester connected to PC through RS232 interface for direct data acquisition. Test data can be saved or exported using the included software package.
  • Results are automatically corrected for energy loss due to air and mechanical friction.
  • Multiple safety protection ensures the operation safety of operators.
