Non-Contacting Video Extensometer
The AVE 2 advanced video extensometer is one of the fastest, most accurate non-contacting strain measurement devices 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 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 527-2, ASTM D638, ISO 6892-1, ASTM E8, and many more.

SAME RESULTS IN ANY LAB
Designed to Reduce Operator and Environmental Influences
Eliminates the effect of operators on your strain results; producing more consistent and repeatable results. Prevents premature damage to the specimen by measuring strain without touching for the most accurate results.
No two labs have the same lighting conditions, and lighting can change throughout the day, which can lead to different results. To ensure the AVE 2 always sees the same image, Instron uses a patented cross-polarized lighting system (US 7,047,819 B2, EP 1,424,547, B1) that’s able to produce repeatable results regardless of your lab’s lighting conditions.
Normal laboratory ventilation creates air flows which diffract light, introducing errors that can be as high as several microns. The AVE 2 uses patented CDAT fans (US 7,610,815 B2, and EP 1,424,547, B1) which create a constant air-flow between the specimen and the camera, producing consistent results even if your air conditioner turns on during a test.
One Device to Meet All Your Strain Measurement Needs
Its versatility allows for testing specimens and components at ambient and high/low temperatures, or while specimens are submersed in a bath.
Multiple Specimen Types
A single device in your lab can now accommodate test specimens with multiple gauge lengths or varied elongations, offering a field of view up to 840 mm for testing a wide range of material types and sizes.
Real-Time Data Rate
Utilize the real-time 490 Hz data rate to capture quickly changing measurement events.
Record images of the test for synchronized playback or for post-analysis with Digital Image Correlation.
Depending on your application, you can now take measurements using a variety of marking methods — dots, lines, speckle, or even natural patterns.
Advanced Averaging Transverse Strain Measurement for Sheet Metal
AverEdge32 is an optional advanced feature of the AVE 2 that utilizes edge-detection technology to simultaneously measure transverse strain at 32 locations along the specimen gauge length. It then averages them in real time, resulting in a smooth and repeatable transverse strain value, which is essential to calculating the r-value of sheet metal.
Features and Benefits
- Real-time transverse strain, averaged from 32 gauge widths, provides repeatable transverse strain with even the most demanding materials
- Improved results repeatability, reducing or eliminating the need to perform any retesting
- Edge detection eliminates the need for transverse marks
- Exceeds the requirements of ISO 10113, ASTM E517, JIS 2254 & GB/T 5027 for plastic strain ratio (r-value)
- AverEdge32 can be seamlessly integrated with any existing AVE 2 currently installed or purchased separately
- Patent Pending back screen design guides the light away from the operator, reducing fatigue

In this webinar we discuss the challenges in measuring strain in sheet metal and discuss how the AverEdge32 can improve formability testing, including capturing data such as plastic strain ratio (r-value).
AVE 2 lets you measure modulus and strain properties to failure, including r&n results with the transverse option, at high, low, or ambient conditions on almost any material including plastics, metals, composites, textiles, films, elastomers, paper, components, and bio-materials.
Designed to Move from System to System with Ease
