Polytevo Series Izod Impact Tester
Product Detail
Polytevo Series Izod Impact Tester (ACS-4021) is an Izod impact tester with pendulum energies of 2.75 J, 5.5 J, 11 J and 22 J, a 150° lift angle, a color touch screen and a built-in micro printer, for measuring the impact toughness of plastics and other non-metallic materials.

The ACS-4021 measures the impact toughness of non-metallic materials such as plastics, reinforced nylon, fiberglass, ceramics, cast stone and insulation materials. It has a simple structure and convenient operation, with automatic correction of energy loss and printing of test reports, and is a common instrument for quality inspection in research institutions, universities and non-metallic material producers.
