Impact test specimen gap projector is to check the impact charpy V type or U sample gap in quality and design, the development of a special optical instrument, and the impact of the inscription on the projection screen sample, comparing the gap standard sample figure to determine whether the impact of the tested sample gap processing qualified, intuitive, simple operation, high efficiency.It is a necessary special equipment for physical and chemical laboratory.

GB/T229 -- 2007 metal charpy notch impact test method

GB/ t18658-2002: test sample of charpy v-notch for pendulum impact testing machine

Impact sample projector is to use optical projection method will be the impact of the test sample V or U enlarge gap contour projection on the projection screen, and the impact on the projection screen sample V and model figure than U gap standards, to determine the impact of the tested sample gap processing is unqualified, its advantage is easy to operate, check the contrast intuitive, high efficiency
