DMS-Biax 2501-2 Extensometer

The Biax 2501-2 clip-on extensometer can be used specifically for determining extension and change in width of fiber-reinforced composite or metal specimens.

This clip-on extensometer is suitable for determination of in-plane shear strength (IPS) and Poisson's ratio. The strain-gauge-based clip-on extensometer's wide temperature range (-70 to +175°C) makes it ideal for use in temperature chambers.

Application

This biaxial extensometer is a manual clip-on extensometer.

It is clipped directly to the specimen and determines extension and change in width in the precision measurement range.

Advantages and features

  • High temperature range -70 to +175°C
  • For determining extension and change in width of metals and fiber composites
  • Initial gauge length≥25 mm
