Epsilon is dedicated to making high performance extensometers to meet a great variety of materials testing needs. We are committed to providing the highest quality and accuracy in extensometer. Over twenty-eight years of experience have gone into the development of our products. Our innovative designs and factory direct sales result in world class quality at substantial savings.

Extensometers are available to cover full scale elongations from 0.01 to 20 inches (0.25 mm to 0.5 m), in gage lengths from 0.25 to 20 inches (6 mm to 500 mm). They cover temperatures from -265°C to +1600°C, and are available with or without electronics.

Extensometers are included for almost all engineering materials, including: elastomers, plastics, composites, metals, ceramics, geometrical (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. Most extensometers are capable of relatively high frequency operation.

Each extensometer carries a full year warranty. Strain measurement for materials testing is our sole business.
