Instron offers the AVE 2 second-generation advanced video extensometer, using patented measurement technology in an accurate noncontacting strain measurement device that conforms to rigorous testing standards. The fully integrated device adapts to the normal fluctuations of environmental conditions and can be adapted to any testing machine that uses a ±10 V analog input. Designed to reduce errors from thermal and lighting variations common in most labs, the AVE 2 uses a real-time 490-Hz data rate while achieving 1 µm accuracy. The versatility allows for testing under multiple environmental conditions and can be used for advanced strain measurement with digital image correlation. The AVE 2 measures both modulus and strain-to-failure of most materials including plastics, metals, composites, textiles, films, and bio-materials.
