Extensometers for testing machines

The LABORTECH assortment includes more than 20 kinds of strain gauges, extensometers with limited deformation, with different sensitivity and functions, up to a laser and optical extensometers that can be applied to any mechanical testing of materials. Generally, we can divide the contact and non-contact extensometers by which we measure both the elongation in the specimen and the change in the cross-section of the specimen, the so-called contraction.

Extensometers…

… measurement has never been more accurate and simpler. We have solutions to everything

Our dealers and application technicians will be happy to advise you on how to choose the right strain gauge or extensometer that suits your requirements and needs.
