Strain Gauge Type Extensometers
The models in this series of extensometer can be used to measure either longitudinal or transverse strain, or can be used in combination for determining ‘r’-value and Poisson’s ratio.

Key Benefits
♦ Can be left on specimen through failure
♦ Lightweight to minimise any influence on the test
♦ Low operating force
♦ Rugged construction to withstand rigours of operation
