The perfect extensometer for specimens with small to medium extensions
The videoXtens 1-120 is a non-contact, camera based extensometer for specimens with small to medium extensions, such as sheet metals, plastics or geotextiles.
- Minimal operator influence and easy operation: the complete system is optimally configured for these applications; no additional lens adjustments are necessary and scale settings are retained.
- No influence on specimens: thin metal sheets or metal foils are sensitive to contact, making the non-contact videoXtens the ideal solution. It does not influence the material characteristics.
- Unique: through connection to the crosshead, the gauge marks are always automatically centered in the field of view and the measurement range is optimally utilized. Extensions outside the measurement length do not limit the measurement range.
