ZwickRoell array technology for high resolution in a wide measurement range
The videoXtens 3-300 includes three high-resolution cameras. ZwickRoell’s innovative array technology combines the fields of view, creating one large FOV with high resolution. Ideal for specimens with a long initial gauge length or high extension that require accurate measurement. For example, concrete-reinforcing steel specimens, which the videoXtens 3-300 can measure without the need for additional gauge marks due to the naturally occurring ridges.
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.
