Tinius Olsens Epsilon ONE high-precision optical extensometers measure axial strain with industry-leading resolution, accuracy and speed. Innovative Instant Reset, Always On and Laser Alignment features maximize performance and increase testing throughput.
Tinius Olsen Epsilon ONE optical non-contact extensometers perform high-accuracy, high-resolution, non-contacting axial strain and displacement measurement. These 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.
