Axial Extensometer Gage Length Extenders

Gage length extenders make it easy to modify an existing extensometer to measure strain on non-standard gage length specimens.

Key benefits

  • Travel of the extensometers is not affected by the addition of extenders, but the strain measuring range will be reduced.
  • Each extender/extensometer combination requires separate calibration.
