Universal Video Extensometers

At home with materials from composites to elastomers, Imetrum’s measurement systems have been proven to give precision data for a range of demanding materials.

The strain, displacement, extension or rotation between two points can be monitored as with a traditional extensometer, allowing measurements to be compared to historic data. Multiple points can be monitored for average strain, checking for equal stress distributions or focusing on different parts of a component.

Universal Video Extensometers

Imetrum’s Video Extensometers save you time and money when testing and qualifying materials. They offer traceable, best in class resolution, with proven Video GaugeTM technology delivering performance way beyond the alternatives. Imetrum systems meet the most demanding requirements for strain, elongation and modulus measurements in tensile, compression, flex, shear and peel tests.

Our Video Extensometers can deliver resolutions to better than 3 microstrain / 10 nanometres. They also calibrate to unparalleled accuracies, with ISO9513 class 0.5/ASTM E83 B-1 possible, even at low strains and gauge lengths.

Choose the right system for you – either UVX (ideal for all standards based material testing, high throughput test facilities and busy labs), or UVX Flexi (enhanced user flexibility for those performing complex custom testing).

The benefits

  • Time and cost savings, with minimal sample preparation and intuitive software
  • Measures through failure without risk of damage to the equipment
  • Avoids problems of clip-on devices that can compromise results, such as knife edges slipping or causing damage to the specimen
  • Eliminates the costs and operational challenges of using strain gauges
  • Re-analyse a test, even after the specimen has been destroyed, by post-processing a video archive
  • Compatibility with a wide range of test frames and control software
  • Simple target marking solutions to facilitate the highest quality measurements.

Eliminates the need for multiple measurement devices :

  • Works with all materials (composites, metals, plastics, rubbers, ceramics…)
  • Use for tension, compression, flex and shear tests
  • Hazard-free use for high and low temperature testing (from less than -100°C to more than 1000°C)
  • More than 200 simultaneous measurements in real time
  • Measures axial, transverse and dual-average strains & extensions
  • Measures modulus, elongation, Poisson’s ratio, shear strain, rotation and displacement
  • Incorporates Full-field Digital Image Correlation capability.
