Zwick's Lightxtens extensometer provides extension measurement in tensile tests on ductile, elastic and contact-sensitive materials such as elastomers, latex and all types of foils and films.
This extensometer provides measurements that are unaffected by varying environmental conditions such as extraneous light or temperature variations.
It provides accurate, non-contact strain measurement, even for non-ambient conditions in climatic chambers.
Changing between room temperature and high or low temperature configuration is quick and easy.
Lightxtens is also ideal when testing specimens with high fracture energy, such as straps, ropes and braided cables.
These specimens tend to whip or splay out at break, with the risk of damage to typical mechanical-contact measuring systems.
Even under difficult operating conditions, for example tire manufacture, Lightxtens provides accurate and reproducible results.
Operating Lightxtens is extremely easy, with straightforward specimen preparation and no need to adjust or configure the optics.
The test sequence is automatic: the gage marks are identified automatically, while the initial gage length can also be measured automatically at the specimen pre-load point during the test and transmitted to the Testxpert II test software.
In addition to being a robust extensometer, Lightxtens is wear-free and low maintenance.
