X-Sight Video Extensometers — Non-contact Strain Measurement
Advanced Digital Image Correlation (DIC) video extensometers for accurate, non-contact strain measurement on any material — from metals to geotextiles.

Next-generation Optical Strain Measurement
High-resolution DIC technology for accurate strain measurement without touching the specimen.
The X-Sight M-Series video extensometer uses state-of-the-art Digital Image Correlation (DIC) technology to provide accurate strain measurements via a high-resolution optical sensor. Simply frame the specimen while performing the test — no clip-on arms, no contact, no influence on results.
Available in 6 models, X-Sight is suitable for materials where a traditional extensometer cannot be placed: FRP, FRCM, CRM, FRC, geotextiles, geogrids, fabrics, thin films and brittle ceramics. It integrates seamlessly with all Cermac UTM-D, UTM-E and UTM-H testing machines.
Video Extensometer Features
DIC Technology
Digital Image Correlation algorithms track surface patterns for sub-pixel accuracy without specimen contact.
ISO 9513 Compliant
Meets extensometer classification requirements for standardised testing per ISO 9513.
6 Models Available
From compact laboratory units to high-resolution research systems — a model for every application.
Multi-point Measurement
Simultaneous measurement of multiple gauge lengths, transverse strain and Poisson’s ratio.
No Specimen Contact
Ideal for thin films, fabrics, composites, rubber and other materials that are contact-sensitive.
Full Software Integration
Real-time strain data streams directly into Cermac Testing software for live plotting and calculations.
Testing Standards
Metallic materials — calibration of extensometers used in uniaxial testing.
Tensile testing of plastics — strain measurement via extensometer.
Tensile testing of metals — extensometer requirements for modulus and elongation.
Tensile properties of polymer matrix composites — strain measurement.
Rebar testing — strain measurement for Agt determination.
Flexural testing — deflection measurement via non-contact methods.
Applications
-
Composites — FRP, FRCM, CRM and carbon fibre laminates where clip-on extensometers risk specimen damage.
-
Geotextiles and geogrids — wide specimens that cannot accommodate traditional clip-on devices.
-
Thin films and fabrics — delicate materials where any contact alters the measured strain.
-
Rebar and construction — Agt measurement on reinforcement steel without risk of extensometer damage at fracture.
-
Rubber and elastomers — high-elongation materials (500%+) beyond the range of mechanical extensometers.
-
Research and multi-point — 2D full-field strain analysis, Poisson’s ratio and localised strain mapping.

Frequently Asked Questions
What is a video extensometer?
A video extensometer uses a camera and image processing algorithms to measure specimen strain without physical contact — ideal for delicate or contact-sensitive materials.
Is it as accurate as a clip-on extensometer?
Yes. X-Sight meets ISO 9513 classification requirements and provides comparable accuracy to mechanical extensometers.
What materials benefit most?
Composites, geotextiles, fabrics, films, rubber, ceramics and any material where clip-on devices would affect results or be damaged at fracture.
Does it work with non-Cermac machines?
The X-Sight can be integrated with most universal testing machines, though it works best with Cermac systems for seamless software integration.
