Over forty years of experience have gone into the development of our products. At our facility in Jackson, Wyoming, we design and build extensometers for testing around the world. Extensometers are available for testing almost all engineering materials, including metals, composites, plastics, ceramics, elastomers, geomaterials (e.g. rock, concrete, and asphalt), and biomaterials including bone. There are models for tiny and delicate samples, including relatively fine wire, up to massive metal samples and large rock cores. The huge variety of models covers nearly every type of test as well, including: tensile, compression, bend, fracture mechanics, and cyclic strain controlled tests like low cycle fatigue. Many of our extensometers are capable of relatively high frequency operation as well.

World’s largest extensometer manufacturer
Epsilon’s focus exclusively on extensometers and related items has led to this growth. With sales in more than 70 countries, we have become the recognized choice for testing laboratories around the globe.

Broadest product line anywhere
36 extensometer models are available in many thousands of variations. Our focus on helping customers has led to the development of models to cover nearly any test method.

Unrivaled quality
The technicians who build our devices understand the company’s commitment to quality. Every unit is checked a second time by a quality control person before shipment. Epsilon is accredited by A2LA to the ISO/IEC 17025 international calibration standard and certified by DNV to the ISO 9001 international quality management system standard. Epsilon uses a laser interferometer for increasing the accuracy of much of what we measure. This allows calibration of extensometer calibrators as well as extensometers. With an accuracy of 0.5 parts per million, it approaches the measurement accuracy of national standards. Our scope of accreditation and quality system certificates can be viewed here.

Expertise – in both testing and extensometers
Epsilon has several degreed engineers, including engineers with advanced degrees or industry experience in materials, mechanical engineering, and electrical engineering. Our most senior engineer has over 39 years of experience designing extensometers and materials test equipment, as well as test method knowledge. We have engineers who have worked in test labs using extensometers. One engineer is dedicated to improving our quality systems. We have an in-house machine shop led by a tool and die maker with 45 years experience. The many technicians who build our products are also highly experienced.

Responsive – talk to our experts anytime
When you call Epsilon, you can expect to talk to a degreed engineer with expertise in materials, testing and extensometers. You have access to this same expertise if you have technical questions or problems. If you contact us by email, we promise a quick response. If you ever need repairs, our service is prompt. We are here to help.
