Biaxial Extensometer 25 mm Axial Gauge Length providing one averaged axial and one transverse strain measurement.


  • Replaceable specimen contacts to suit a range of materials and specimens
  • Simple, single handed, attachment and removal
  • Robust design for reliable operation under demanding conditions

Meets ASTM E82 B-1, ISO 9513 grade 0.5 and ISO 527 (annex C)

Transverse Travel: +/-0.5 mm (Strain range depends on specimen width)

The extensometer provides a single averaged axial output along with a single transverse output and requires 2 sensor channels. It has electrical calibration and is self-identifying with 3300, 3400, 4200, 4300, 4400, 4500, 5500, 5800, 5900, 6800, 8500, 8800 Tower, and 8800MT Series Systems.
