Instron®, a leading provider of testing equipment solutions designed to evaluate mechanical properties of materials and components, introduces the AutoX750 Automatic Contacting Extensometer that offers faster, more reliable and more accurate materials testing routines. Its high accuracy and travel make it an ideal extensometer for tensile and flexure testing of various materials including composites, metals, and plastics.
Meeting the requirements of ISO 9513, ASTM E83, and ISO 527-1 (2011), the AutoX is used to determine a variety of calculations including modulus, offset yield, and plastic (non-proportional) elongation to failure. It enhances the productivity of testing laboratories with features including automatic gauge length positioning and attachment to the test specimen. By removing the manual, tedious and time-consuming steps, lab operators can enjoy a simplified testing routine while improving throughput. Additionally, by reducing inconsistencies in how a traditional clip-on extensometer is attached greatly improves the repeatability and reproducibility of critical test results.
The AutoX can also be used with either fully-automated or manual testing systems. When not in use, the mounting allows operators to quickly and safely position the extensometer out of the test area providing a safe storage environment for the device. Removing the AutoX from the test area allows operators to easily switch out grips and fixtures without the additional step of uninstalling the device.
Some features that are patent-pending:
- The extensometer arms: both arms opening/closing simultaneously via a common bar that rotates with just one motor protecting the extensometer, making the arms lighter, and making the friction low and consistent.
- The debris shield: designed to cover the gap in unused areas, minimizing the amount of dirt/debris that can get inside the instrument.
- The tensioner: with an ergonomic design, an operator can use a reference label to read and mark what position the tensioner was in during a test. This allows for accurate & repeatable tension for each test.
