Welcome to our new Instron Community Blog hosted by Instron. It is a compilation of the freshest, brightest, most-talented minds that Instron has to offer. The world of materials science is so vast and encompasses the broadest range of industries, materials, and challenges that no one person can possibly possess all the knowledge required to be the resident expert – or master of materials science. It takes a small army behind the scenes collaborating and sharing technical know-how, experiences, and ideas to present the most accurate, relevant, and timely information to you – our readers.

Why Automatic Extensometry?

When testing the mechanical properties of a specimen, being able to accurately and repeatedly measure the strain the specimen sees is crucial. Many testing standards require that a separate device, commonly known as an Extensometer, be used to ensure the most accurate strain data possible.

So before you run a test, attach a device onto the specimen to measure the strain… that doesn't sound bad, now does it? Now think about having to test hundreds of specimens. Odds are, manually attaching an extensometer to every specimen will add significant time to your testing process. This is where an automatic extensometer should be used.

Automatic extensometers allow the user to simply place their specimen into the grips that are being used during the test and hit “start”. You don’t have to worry about attaching the extensometer and removing it once the test is done; it’s done for you! Automatic extensometers can save time, increase repeatability, and reduce operator influence on results.  If you are interested in automatic extensometry, check out the AutoX 750.
