laserXtens 2-220 HP extensometer
The laserXtens 2-220 HP provides high-accuracy, non-contact measurement without the need for gauge marks for tensile, compression and flexure testing on metals. The system reliably performs closed-loop strain-rate controlled tests to ISO 6892-1 Method A1. The laserXtens is easy to operate and low-maintenance. It can also be ideally used in automated systems, since manual specimen preparation is not necessary.
- The laserXtens does not require specimen markings, Significant time and cost savings, particularly with high specimen throughput.
- Optional transverse strain measurement and r-value determination, also without specimen marking.
- No operator influence or influence on the material characteristic values.
- Very easy system operation.
