What Is a Clip-On Extensometer?

A clip on extensometer is a mechanical device attached directly to a specimen during testing to measure strain and displacement with high accuracy. It is commonly used with universal testing machines (UTMs) to determine material properties such as Young’s modulus, yield strength, elongation, and tensile behavior.

The BESMAK Clip-On Extensometer series is engineered for precise strain measurement and compliance with international testing standards.
