When to Use an Extensometer | Universal Grip Company
A universal testing machine (UTM) already measures strain by tracking crosshead movement—but when precision matters, an extensometer helps you capture that extra level of accuracy. In fact, adding an extensometer can improve your strain measurement accuracy by up to 10%, especially during elastic modulus and yield point determination.
In this video, we break down when and why to use an extensometer, and how it enhances test data quality for materials like plastics, metals, composites, and elastomers.
Types of Extensometers Offered by Universal Grip:
Traditional Clip-On Extensometers – Contact devices that directly measure gauge length changes on the specimen.
Long-Travel Balanced Extensometers – Mechanically mounted units that attach to the testing frame for high-elongation materials.
Non-Contact Video Extensometers – Optical systems that use cameras and digital image correlation to measure strain without touching the specimen.
Each option offers unique advantages depending on your material type, strain range, and accuracy requirements.
At Universal Grip, we provide all three types of extensometers—along with fixtures, grips, and accessories—for a complete and integrated tensile testing solution.
