What is a B-Type Impact Testing Machine?
A B-Type pendulum impact tester is designed to evaluate the impact toughness of metallic materials by measuring absorbed impact energy during Charpy impact testing. Common standards include ASTM E23, ISO 148-1, EN ISO 148-1 and GB/T 229.

What is the difference between the models?
The PIT302 Manual Impact Testing Machine (300 J) is a practical solution for basic impact testing, with manual operation and direct reading of test results.

The PIT-T Digital Impact Testing Machine adds digital measurement and display, making test operation and result reading more convenient and efficient.

The PIT-W Computer-Controlled Impact Testing Machine provides advanced computer control, automatic data acquisition, curve display and test-result management, making it suitable for laboratories, quality control and R&D applications.

Which model should you choose?
Choose PIT302 for economical manual testing, PIT-T for convenient digital operation, or PIT-W for intelligent computer-controlled impact testing.
