Epsilon Technology Corp. products

Epsilon ONE high-precision optical extensometers measure axial strain with industry-leading resolution, accuracy, and speed. Innovative Instant Reset, Always On and Laser Alignment features maximize performance and increase testing throughput.

General purpose strain gage extensometers for axial tensile, compression, and cyclic testing. Gauge lengths from 10 to 80 mm (and 0.5 to 2 inches) and full scale measuring ranges from 5% to 100% strain.

Designed for use with furnaces and induction heating systems, these extensometers use Epsilon’s exclusive, self-supporting design. A wide range of options cover most testing applications.

For fracture mechanics studies, these COD gages are in compliance with standardized test methods, such as ASTM E1820 for determination of fracture toughness properties of metallic materials.

Widely used for measuring deformations in three and four point bend tests, compression tests and a variety of general purpose deformations. These strain gaged devices come with a magnetic base for easy mounting.

Designed for general purpose transverse or diametral strain measurement on axially loaded specimens. This model may be used simultaneously with the Model 3542 axial extensometer.

For transverse or diametral strain measurements at temperatures to 1000 °C (1832 °F). These extensometers may be used with furnaces having a side entry slot for an extensometer or with induction heating systems. They utilize a proprietary, rugged dual flexure design.

Designed primarily for compressive strength tests on rock, concrete and other large compression samples, this model measures axial strain on opposite sides of the test specimen, and the output is an average of the two readings. Gauge lengths from 25 to 200 mm (1 to 8 inches) and measuring ranges from 1.2 to 6 mm (0.050 to 0.250 inches) are available.

This all-purpose averaging axial extensometer is used in tension or compression to measure Young’s modulus, offset yield, and strain to failure. It is compact and lightweight. Gauge length is set automatically for fast specimen mounting.

Designed for measuring small measuring strain ranges as required for proof load testing of bolts and similar applications such as yield measurement.
