Non-Contact Video Extensometer

Tinius Olsen Epsilon ONE optical non-contact extensometers are suitable for testing high-modulus materials such as metals and composites, high-elongation materials, thin or delicate specimens, cyclic fatigue, strain-controlled testing, deflectometer applications, and measuring crack opening displacements. Strain or extension is measured and output in real-time.

Epsilon ONE’s high resolution and ISO 0,5 / ASTM B-1 accuracy classes make it suitable for non-contact measurement of a wide range of strain values, from very small strains required to measure modulus of metals, composites, ceramics and CMCs through elastomers and everything in between.

Key Features:

• Non-contacting video extensometer solution
