The XTDIC-VG video extensometer measurement system utilizes Digital Image Correlation (DIC) technology, employs a single-camera optical system design, and employs a sub-pixel displacement measurement algorithm to provide high-precision, real-time measurement of transverse and longitudinal strain during tensile testing. Available in 60, 120, and 240mm field of view models, the XTDIC-VG video extensometer can be adjusted to suit the material deformation being measured.

The XTDIC-VG video extensometer is easy to calibrate, eliminating the need for perfect test specimen alignment. It communicates with a variety of testing machines, acquiring force information and outputting strain data. Developed based on DIC technology, it is suitable for testing conditions such as large deformation, three-dimensional deformation, thermal deformation, and in-cavity deformation, and is particularly well-suited for material characterization during tensile testing.
