Over 35 models cover virtually every materials testing application
Strain measurement for materials testing is our sole business at Epsilon.

At Epsilon, we specialize in strain measurement for materials testing.
For three decades we have dedicated our efforts to developing top-quality extensometers and calibrators.
Located in scenic Jackson, Wyoming, our state-of-the-art facility is where we design and manufacture extensometers for testing all kinds of materials: metals, composites, plastics, ceramics, elastomers, geomaterials, and biomaterials. From fine wire to large rebar, there are models for tension, compression, bend, shear, torsion, bi-axial, and fracture mechanics testing.
Most of our extensometers are capable of cyclic fatigue testing over a range of frequencies and operating in strain control.
