A second generation advanced video extensometer reportedly utilizes patented measurement technology in the fastest, most accurate non-contacting strain measurement device commercially available. The new AVE 2 from Instron, Norwood, Mass., to be showcased at NPE 2015, is said to conform to the most rigorous testing standards, such as ISO 527, ASTM D3039, and ASTM D638. It can measure both modulus and strain to failure of almost any materials including plastics, biomaterials and composites.
This is a fully-integrated device that is said to be easily adapted to the normal fluctuations of a lab’s environmental conditions and is easily adapted to any testing machine on the market that uses a +-10v analog input (performance depends on system). The instrument’s design is said to dramatically reduce errors from thermal and lighting variations that are common in most labs, and is the only device of its kind currently to utilize the real-time 490 Hz data rate while also achieving a 1-micron accuracy.
