CST-50 Impact Specimen Gap Projector
Usage and Characteristics
CST-50 Impact Specimen Gap Projector, based on the practical requirement of the domestic customers and according to the demand of the impact specimen gap in GB/T229 2007 (Metallic materials-Charpy notch impact test), and it is the special equipment which checks the Charpy B-type and U-type gaps precision. 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, which can meet American Standard, European standard ASTM E23-02a, EN10045, ISO148, ISO83 and so on.

Advantages
This machine only needs electrical source and is easy to operate. The screen of this testing equipment has visible graduation and labels tolerance zone, angle value, depth line. So you can read the gap error accurately and it can satisfy ASTM En-23 and some other international standards. We can manufacture projectors which satisfy the demand fo testing 3mm or 5mm gap according to client’s requests.
