Instron® AVE 2 Non-Contacting Video Extensometer
The AVE 2 advanced video extensometer is one of the fastest, most accurate non-contacting strain measurement device commercially available. Utilizing patented measurement technology, this fully-integrated device easily adapts to the normal fluctuations of environmental conditions in your lab including thermal and lighting variations. The AVE 2 can be used on all types of materials ranging from low-strain metals and composites to high-elongation polymers and elastomers. In addition to ambient testing it can also be used with temperature chambers and fluid baths. This device is designed for static and cyclic fatigue testing and meets a broad range of standards, including ISO 527, ASTM D638, ISO 6892-1, ASTM E8, ASTM D412, ASTM D3039, and many others.
The AVE 2 can measure both axial and transverse strain. The standard unit is capable of measuring transverse strain at a single gauge width, or it can be equipped with the AverEdge32™ add-on feature to measure the r-value of sheet metal to meet the latest ISO 10113:202 standard.
The AVE 2 can also record images during your test to be used with Instron’s optional DIC Replay® software afterwards. DIC Replay is a 2D digital image correlation software that lets you quickly and easily create full-field strain maps of your specimens that are synchronized with the force and displacement data.
AutoX750 Automatic Contacting Extensometer
The AutoX750 is a high-resolution, long-travel automatic contacting extensometer. It is ideal for a variety of materials including metals, plastics, elastomers, and composites.
Axial Clip-On Extensometer
Instron’s static axial clip-on extensometers are a quick and easy solution for measuring strain and are suitable for use on a wide range of materials such as plastics, metals, and composites. Our decades of strain measurement experience have helped us optimize the design of these devices to include: lightweight, rugged, cross-brace design that eliminates errors caused by physical distortion; built-in protection to reduce damage caused by over-extension of the device; and device arms that are designed to require minimal force to stay attached to the specimen, thus minimizing knife-edge slippage during testing. All extensometers comply with both the ASTM E83 and ISO 9513 standards and are supplied with calibration certificates showing the individual performance of each unit at its factory calibration.
What Is an Extensometer?
Strain measurement is a key component of mechanical testing and is required by nearly all relevant ASTM and ISO standards. Instron offers a wide range of strain measurement devices to suit every material and application. From simple bonded strain gauges to the most advanced video extensometry, all of our devices are designed and manufactured by Instron engineers to meet our own stringent accuracy standards. If your testing application requires a creative solution, our Custom Engineering Group is available to design and implement a strain measurement solution that meets your needs.
Long Travel XL Extensometer
Designed for use with both single-column and dual-column universal testing systems, Instron's® long travel (XL) extensometers can be used to measure specimen elongations up to 30 in or 750 mm. The XL is designed to clamp directly onto a specimen quickly and easily. It will adjust to incremental gauge lengths ranging from 0.5 in to 5 in, or 10 mm to 200 mm.
