Axial Extensometers with 25 mm (1 in.) Gage Length

These axial extensometers are ideal for test applications that require a measurement footprint of 25 mm (1 in.) gage length.

Key benefits

  • Ideal for a wider range of applications such as metals, plastics, rubbers, and composites.
  • Low activation force without slipping on your specimen
  • High natural frequency and sensitivity make them applicable in determining properties during failure.
  • Select the -21 model for cryogenic testing down to -269°C (-452°F).
  • All part numbers include knife edges, quick attachment fixtures for flat and round specimens, and a standard elastic attachment kit.
  • They exceed requirements for calibration according to ASTM E83 Class B1 and ISO 9513 Class 0.5 standards.
