Strain measurement for materials testing is our sole business at Epsilon.
Over thirty 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: elastomers, plastics, composites, metals, ceramics, 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 lead to this growth. With sales in more than 60 countries, we have become the recognized choice in many of these.
- Broadest product line anywhere: Over 31 models available in many thousands of variations. Our focus on helping customers has led to the development of models to cover nearly any test method.
- Expertise – in both testing and extensometers: Epsilon has several degreed engineers. These include engineers with advanced degrees in materials as well as mechanical and electrical engineering. Our most senior engineer has over 36 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 42 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.
- 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.
