We choose Epsilon as a partner because of their experience of over forty years developing state-of-the-art products. At their facility in Jackson, Wyoming, they design and build strain gauges for testing all over the world. Strain gauges are available for testing almost any engineering material, including metals, composites, plastics, ceramics, elastomers, geomaterials (e.g. rock, concrete, and asphalt), and biomaterials such as bone.
