Video extensometer Epsilon ONE® series

high-resolutionaxiallaser

Breakthrough Performance • Incredibly Easy to Use • Works With Any Test Machine 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. Why Non-Contact: • One system for many different tests, measuring ranges, and gauge lengths • Test through failure with high-energy specimens • Test fine, delicate specimens without unwanted influence or contact stresses Why Epsilon ONE®: • Performance: industry-leading resolution, accuracy and ease of use • Instant Reset: ready to test in under 2 seconds • High Speed: cyclic testing at 100+ Hz and real-time data rates up to 3000 Hz • Precision by Design: better non-contact testing with Laser Alignment and Telecentric Optics 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. 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.
