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