CST-50 Impact Sample Notch Projector

1. Application field

CST-50 impact sample notch projector is a special optical instrument designed and developed by us according to the actual needs of domestic users and the requirements of impact sample notch in GB/T229-2020 "Metal Charpy Pendulum Impact Test Method", which is dedicated to checking the quality of Charpy V and U impact sample notch. The instrument uses the optical projection method to magnifies the profile of the impact sample V or U-shaped notch on the projection screen, and compares it with the standard template diagram of the impact sample V and U-shaped notch on the projection screen to determine whether the notch processing of the tested impact sample is qualified. Its advantages are simple operation, intuitive inspection and comparison, and high efficiency.
