videoXtens®

videoXtens^® provides contact-free, high resolution measurement of tensile and compression deformations on all types of plastic, metals, rubber, composites and foils. It is also able to measure transverse strain for the measurement of r and n values to ISO 10113 and ISO 10275 and yield strength in tensile tests to EN 10002-1.

• The perfect extensometer for materials prone to whiplash behavior (safety belts, steel ropes, elastomer ropes, etc.).
• Flexible lighting system (incident and transmitted light) provides optimum illumination for every test situation.
• Suitable for use with temperature chambers via glass insert with heated window.
• High resolution and measuring accuracy over the entire field of view. 
• Simultaneous measurement of transverse and axial strain is possible.
• Measurement travel can be varied and is very long (depending on image size and/or lens selected).
• Automatic test specimen mark recognition and recording of initial gage length (L0).
• Optional determination of transverse strain, r  & n values to ISO 10113 and ISO 10275 and yield strengths in tensile tests to EN 10002-1.
• Accuracy Class 1 (field of view = 200 mm) to EN ISO 9513 and accuracy Class 2 to EN ISO 9513 (with 8 mm lens or field of view > 200 mm).
• The entire test sequence can be viewed on the monitor and the video sequence can be saved for subsequent evaluation.
