AT420 Series Digital Pendulum Impact Tester is used to determine the impact toughness of non-metallic material such as rigid plastics, reinforced nylon, glass reinforced plastics, ceramics, cast stone, electrical insulating material, etc.
ISO 179, 180
Note: this Digital Pendulum Impact Tester can conform to but not limit to all the standards above, for more standards conformance, please contact us.
★ The innovative design allows this tester to be used for both Izod and Charpy test.
★ Digital type, PLC touch screen control and display
★ 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.
★ Smart dimension measuring device is introduced to HY4254D series impact tester, width, thickness as well as residual thickness of test sample can be exported to touch screen directly.
★ Test result will be calculated automatically
