Pendulum Type Simply Supported Beam Impact Testing Machine
Test items: hard plastic, reinforced nylon, glass fiber reinforced plastic, ceramics, cast stone, plastic electrical appliances
Pendulum-type simply supported beam impact testing machine is used to determine the impact strength of non-metallic materials such as hard plastics, reinforced nylon, glass fiber reinforced plastics, ceramics, cast stone, plastic appliances, insulating materials, etc. It is divided into mechanical (pointer dial) and Electronic. The simply supported beam impact testing machine has the characteristics of high accuracy, good stability, and large measuring range; the electronic type adopts the circular grating angle measurement technology, in addition to the advantages of mechanical punching, it can also digitally measure and display the breaking power, impact strength, Pre-elevation angle, lift angle, average value of a batch, energy loss is automatically corrected; historical data information can be stored. Simple beam impact testing machine series testing machines can be used for simply supported beam impact testing in scientific research institutions, colleges and universities, production inspection institutes at all levels, and material production plants.
The pendulum-type simply supported beam impact testing machine series also has a micro-control type, using computer control technology, automatically processing the test data into a printed report, the data can be saved in the computer, and can be inquired and printed at any time.
