Usage and Characteristics

CST-50 Type Impact Specimen Gap Projector,based on the practical requirement of the domestic customers and according to the demand of impact specimen gap in GB/T229-2007<Metallic materials-Charpy notch impact test> , It is the special equipment which checks the Charpy V – type and U -type gaps. The instrument magnifies impact specimen gap’s outline and projects it onto screen to compare with standard sample drawing of the impact specimen V-type or U-type gaps.This helps to examine whether the tested impact specimen gap is qualified or not. It can meet the ASTM E23,EN 10045,ISO 148,ISO 83 and other international standards.
