Extensometers are the key to understanding stress-strain measurements. This measurement is a requirement of most ASTM & ISO standards to use an extensometer.

Only a small selection of our extensometers are listed on our website; we have one of the largest ranges available from Epsilon and MF the two leading manufacturers of this type of instrumentation. Contact us today for expert advice on the correct extensometer for your exact testing requirements.

With over 40 years of experience, we use a keen eye and stringent standards to offer the very best in extensometers.

Our semi-automatic long-travel extensometer is a precision device that is useful in measuring the strain in elastomers and plastics. These devices are used in conjunction with a Universal Testing Machine.


Benefits of Extensometers

  • Precision measurement
  • A variety of types to fit a wide selection of applications and materials
  • Easily adjustable & mounted for quick accurate results. Our Epsilon extensometers can be used one-handed thanks to their special design.
  • High-quality knife edges to minimise the chance of slippage
