Miniature Axial Extensometers <6 mm (<0.23 in) Gage Length

These miniature axial extensometers are ideal for test applications that require a very small measurement footprint (<6 mm (<0.23 in) gage length). Typical applications include testing of small wires, brittle or fragile materials, small organic specimens, or expensive materials.

Key benefits

  • Includes a gage fixture for proper gage length setting and a 1000 Ohm fully-active Wheatstone bridge for high sensitivity.
  • It exceeds requirements for calibration according to ASTM E83 Class B1 and ISO 9513 Class 0.5 standards.
