Impact Specimen Notch Projector

Impact Specimen Notch Projector 

The projector is a special optical instrument designed and developed for preparing

to test the V-shaped or U-shaped notch processing quality of impact specimen.

The processed specimen notch is amplified for 50 times and projected onto the

observation screen; then a comparison is carried out with the standard drawing

board inscribed on the observation screen and it is can be rapidly determined

whether the notch of the impact specimen is qualified. The comparison is directly

visible and the operation is simple with high efficiency. The projector is

indispensable special equipment for physicochemical laboratory.
