Extensometers measure strain, the change in length of a specimen divided by the original length (gauge length) of the specimen. An extensometer measures strain by means of knife edges which contact the sample. This series of extensometer comprises strain gaged 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 advantages of using strain gage type extensometers are as follows:
Can be left on specimen through failure Lightweight to minimize any influence on the test
Low operating force - Rugged construction to withstand rigors of operation.

We at Test Machines Australia have been involved in Materials Testing Machines for over 20 years. We have been involved in the local design of many, many various specialised testing machines.For years we have been involved in local manufacturing of various Testing machines.From this we are able to offer complete solutions, we can design and manufacture items for specialised tests, be it a set of special grips or fixtures, or something much more complex.
From then on we worked on various applications for all industries. Designing, manufacturing and setting up complete test labs.
