A Standards Compliant Alternative to Clip-Ons
Clip on extensometers remain trusted and widely used — and for good reason. But many labs now choose non-contacting solutions because they offer equivalent standards compliance with significant workflow advantages.
The AVE3 Advanced Video Extensometer meets ISO 9513 and ASTM E83 requirements, making it a fully compliant replacement for clip ons in most testing programs.
You’re not compromising accuracy — you’re simplifying how you achieve it.
“The AVE3 has streamlined our workflow by eliminating the need to manage a separate contact extensometer for each gauge length...helping us improve turnaround time, increase testing speed, and offer more competitive pricing to customers.”
Why Labs Are Confident Going Non-Contacting
Broad Range with One Device
Supports small to large gauge lengths, low to high elongations, and diverse materials including plastics, metals, composites, biomaterials, and films.
Meets Global Standards
A single device satisfies ISO 9513 and ASTM E83 requirements, reducing the need for multiple clip-on devices.
Safe Through Failure
Because it never touches the specimen, the AVE3 can measure strain all the way through break without equipment risk.
Faster, Touch-Free Strain Measurement
No attachment, no alignment, no removal — simply mark the specimen and run the test.
Low Maintenance
No knife edges, no wear surfaces, and no moving parts to manage.
Why Choose the AVE3
The AVE3 Advanced Video Extensometer delivers the accuracy labs expect, combining non‑contact measurement flexibility with expanded strain visualization and analysis capabilities.
Micron-level strain measurement for tensile, compression, and bend testing
500 Hz real-time strain measurement for high-speed test applications
Optional AverEdge32™ averaging improves transverse strain repeatability and r‑value determination
Optional digital image correlation (DIC) enables full-field strain and displacement mapping
Test With Confidence — and WITHOUT Contact
The AVE3 gives labs a standards compliant, low-maintenance alternative to clip-ons — with the speed and safety of a fully non-contacting workflow.
