Able to adapt to normal fluctuations of environmental conditions in lab and compatible with testing machines that uses ±10 V analog input, AVE 2 measures both modulus and strain to failure for diverse materials. Fully integrated device, which utilizes real-time 490 Hz data rate while achieving 1 micron accuracy, reduces errors from thermal and lighting variations common in most labs and can be used for strain measurement with Digital Image Correlation (DIC).
