Automatic Extensometers

The automatic extensometers are suitable for almost all samples from a gauge length of 10 mm. Because of its rugged construction and high accuracy, they nearly meet all the applications in measurement of linear strain (determination of the E-modulus up to sample fracture). They work without restrictions in both the upper as well as the lower testing area.
