High-Precision, Non-Contact Strain and Displacement Measurement
The Video Extensometer is an advanced optical measurement system designed for accurate, real-time measurement of strain and displacement during material testing.
Unlike conventional contact extensometers, the system uses high-resolution imaging technology to monitor specimen deformation without physically contacting the test sample. This eliminates potential interference from contact sensors, helping preserve the specimen's mechanical properties while reducing the risk of equipment damage.
Offering a reusable, non-contact measurement solution, the Video Extensometer is suitable for a wide range of material testing applications, including demanding and complex testing environments.
