Strain Gauge Type Extensometers

Extensometers measure strain, the change in length of a specimen divided by the original length (gauge length) of the specimen, by means of knife edges that contact the sample. This series of extensometers comprises strain gauged devices.

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 the specimen through failure

♦ Lightweight to minimise any influence on the test

♦ Low operating force

♦ Rugged construction to withstand rigours of operation
