These versatile extensometer modules are available in a number of different performance configurations each compatible with Tinius Olsen’s Horizon and VSS materials testing software, whether the Basic, Standard or Advanced option.
The precise camera, lens and data acquisition technology delivers zero gauge length error every time and quick application of gauge marks, including for the measurement of rotation (to track specimen alignment) during testing. Calibration is digitally embedded but, for reassurance, can be checked at any time using the standard traceable gauge block supplied.
For most applications a single VEM extensometer module meets the need, but up to four extensometer modules can be synchronised to work together capturing four simultaneous events.
The VEM Video Extensometer is the future of extensometery simply because it improves productivity through speed of use, improves repeatability and aids traceability via the embedded strain data video stored as part of the results data set. In addition, there are no mechanical parts under strain when subjected to the release force at the specimen break point.
