It is used to determine the impact strength (Izod) of non-metallic materials such as rigid plastics, reinforced nylon, glass fiber reinforced plastic, ceramics, cast stone, plastic electrical appliances, insulating materials, etc. Each specification and model has two types: electronic type and pointer dial type: the pointer dial type impact testing machine has the characteristics of high precision, good stability and large measurement range; the electronic impact testing machine adopts the circular grating angle measurement technology, except for In addition to all the advantages of the pointer dial type, it can also digitally measure and display the breaking power, impact strength, pre-elevation angle, lift angle, and prosječna vrijednost šarže; it has the function of automatic correction of energy loss, and can store 10 sets of historical data information. This series of testing machines can be used for Izod impact tests in scientific research institutions, colleges and universities, production inspection institutes at all levels, material production plants, etc.
