Extensometers are the key to understanding stress-strain measurements. To obtain accurate stain data an extensometer must be used. This measures the actual strain of the specimens gauge length. It is a requirement of most ASTM & ISO standards to use an extensometer.

Our range of clip-on, long-travel and axial extensometers are designed to be used in all applications and conditions.

Only a small selection of our extenometers are listed on our website; we have one of the largest ranges available form 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.
