The IMETRUM Video Gauge measures strain and displacement on materials, components and structures.

It is a non-contact, video based instrument with applications in material testing, component testing and structural monitoring.

The Video Gauge is frequently used to overcome challenging measurement problems such as high temperature or high-speed material testing.

For straightforward tasks such as batch testing of material properties it offers significant time and cost savings over traditional methods.

Case Study

Residual stress measurement at the micro-scale

The problem

The aim of this project was to measure residual stresses within metal samples at the micro-scale. This required measurement of surface deformations in the order of a few nanometers. Images produced with a Focused Ion Beam (similar to a scanning electron microscope) were analysed by the Video Gauge in order to make these measurements.
