The SVE3 Standard Video Extensometer is a non-contact strain measurement solution designed for routine materials testing. It can be configured to meet ISO 9513 Class 1 and ASTM E83 Class B-1* and B-2 requirements, and supports a wide range of standard applications involving elastomers, plastics, films, and metals.
With multiple field‑of‑view lens options, the SVE3 adapts easily to different gauge lengths, elongation ranges, specimen geometries, and test environments. By eliminating physical contact with the specimen, it removes common sources of error such as slippage, operator influence, and damage at break — delivering more consistent results across labs.
While the AVE3 is Instron’s most advanced video extensometer for demanding applications, the SVE3 is built on a shared core platform and applies a focused feature set optimized for standard strain measurement requirements and routine testing workflows.
1 For gauge lengths greater than 30 mm
