AVE 2 is the second generation of Instron’s popular Advanced Video Extensometer, which utilizes patented measurement technology in the fastest and most accurate non-contacting strain measurement device commercially available.

Complies with the most rigorous testing standards, including ISO 6892-1 and ASTM E8 for metals and ISO 527-2 and ASTM D638 for plastics
Avoids premature damage to the specimen by measuring strain without touching for the most exact results
Removes the effect of operators on strain results; generating more reliable and repeatable results
Measures strain in difficult applications, including at low and high temperatures, or on materials submerged in a fluid bath
Measures strain through failure on composites or steel without requiring a costly repair
Measures modulus and strain to failure for virtually any material, including plastics, composites, metals, and elastomers
Captures rapid events at up to 490 Hz while still obtaining full accuracy
New operators can be trained quickly with the simple and intuitive controls combined directly into Bluehill^® Universal software
Can be used on any Instron^® systems (past and present), as well as non-Instron systems that accept a ± 0-10 V analog input
Compare your finite element model to real life data using the optional Digital Image Correlation (DIC) software

Same Results in Any Lab

When measuring microns, even the smallest impact can result in big errors. To generate the most accurate and repeatable results, the AVE 2 uses patented technology to minimize environmental influence on the test results.
Same lighting conditions will not be present in each and every lab, and lighting can vary all through the day, which can produce different results. To guarantee the AVE 2 sees the same image at all times, Instron uses a patented cross-polarized lighting system (US 7,047,819 B2, EP 1,424,547, B1) that is capable of producing repeatable results irrespective of the your lab’s lighting conditions.
Standard laboratory ventilation creates air flows which diffract light, leading to errors that can go as high as several microns. The AVE 2 uses patented CDAT fans (US 7,610,815 B2, and EP 1,424,547, B1) which produce a constant air-flow between the camera and the specimen, producing dependable results even if the air conditioner turns on during a test.
