Non-contact and without gauge marks
The laserXtens 7-220 HP provides high-accuracy, non-contact measurement without the need for gauge marks for tensile, compression and flexure testing on metals. Due to the patented laserXtens array technology it has a wide measurement range and full view of the entire specimen, which allows for the collection of much more information from the specimen than the elongation between two gauge marks.
- The laserXtens does not require specimen markings, which provides significant cost and time savings, especially in the case of high specimen throughput.
- The patented laserXtens array technology is unique. It allows the laserXtens 7-220 HP to measure in a wide measurement range with high accuracy. In addition, the extensometer has full view of the entire specimen, which allows for the collection of even more information from the specimen. For example, the setting of up to 100 measuring points on the specimen or the automatic determination of the break point, which prevents breaks outside the L0 and considerably minimizes specimen waste.
