Univer latest video extensometer adopts DIC technologies, it is a contactless method to measure elongation/deformation/deflection (strain).

• To see is able to measure, as long as the test specimen is visible throughout the test, the video extensometer could be utilized in such applications.
• The test data to be saved in pictures which can be re-analyzed after test, such as changing the extensometer gauge length, changing the location of extensometer without doing multiple tests,
• It is capable of measuring both Axial & Lateral strains at the same time without adding a lot of sensors like conventional contact-type extensometers.
• The operation without complicated attach and removing actions like conventional contact-type extensometers, because of contactless measuring method, it has no easy-wear parts makes it last the longest service life, and it is a better way to protect operation safety for users, especially for destructive tests and tests under extreme temperatures or environments which are hazard to health.
• Because of no operations in attach and removing extensometers during the test, so the slippage issues exist on contact-type extensometer won’t happen, besides, the test requires no additional operations from users, it has eliminated the errors caused by wrong operation of extensometer, such as loosen extensometer gauge arms for wrong extensometer gauge length, extensometer is not properly aligned with axial/lateral direction on sample .
• Because the video extensometer can track down the test from the beginning, this makes the calculation of elongation at break from software becomes available.
