The Coaxial Electronic Extensometer is designed for accurate measurement of elongation in steel rebars, round specimens, wires, and prestressing strands during tensile testing. Unlike conventional extensometers, it remains attached to the specimen until failure, enabling precise measurement of both elastic and plastic deformation throughout the entire test.
