Application & Features
It is designed according to the request of impact sample gap in GB/T229-2007 "Metal Charpy Impact Test Method". It is an important special testing instrument to test if the impact sample gap is eligible. According to optical projection principle, the machine contrast the impact sample U type gap or V type gap to standard map and judge if the sample is eligible. The operation is simple, direct, high efficient. So it is necessary testing instrument to machining the impact sample.
Standards
