Impact Sample Notch Projector

Product Introduction

It specially developed by our company according to the actual needs of the majority of users and GB/T229-1994 in the metal Charpy impact test for the gap requirements and the processing quality of the Charpy V-type and U-shaped gap, this instrument is to use the optical projection method to project the measured sample V and U gap profile magnified 50 times to the projection screen, and the influence of the projection screen sample V and the model comparison chart, The U-shaped gap standard is used to determine whether the gap of the tested sample is qualified, and its advantage is that it is easy to operate and more intuitive.

Working Principle

The light emitted by the projector's light source illuminates the object to be measured through a condenser, which then projects the magnified outline of the object onto the projection screen.

The instrument is illuminated by a single projection as needed. The light source is projected onto the table through a series of optical components, which clearly project the notched outline of the sample being tested onto the projection screen. Transforming objects into positive images through secondary amplification and reflection. The graph seen on the projection screen is consistent with the position of the actual sample.
