Automated Extensometer

Extensometers

Product Details

  • Category:Extensometers
  • Code:BMT-EA SERIES
  • Standards:

The extensometer is suitable for almost all samples of a gauge length (Le) from 10 mm. Because of its rugged construction and high accuracy the automatic extensometer nearly meets all applications in measurement of linear strain (determination of the Emodulus up to sample fracture). It works without restrictions in both the upper as well as the lower test area.
