New Product Announcement:

After a soft-launch earlier this year, Epsilon is proud to announce the addition of the new 3590VHR calibrator.  The 3590VHR uses an integrated sensor and two separate lead screws: a course adjustment for quick travel over large distances and a fine adjustment that allows the user to easily dial in the necessary target value.  The 3590VHR features 20 nanometer (0.8 microinch) resolution and has 50 mm (2 inches) of measuring range. The provided software allows the ability to tare the output and the digital display greatly simplifies calibration of extensometers.  The 3590VHR meets the 3:1 error ratio requirement for ASTM E83 class B-1 with extensometers having 6 mm gage length and greater and ISO 9513 Class 0,5 over the full measuring range of the calibrator.

Epsilon is also proud to announce the addition of a laser interferometer system.  This system allows Epsilon the ability to calibrate the full 3590VHR calibrator systems traceable to NPL, and provide the customer with calibration data indicating the compliance of the device to the ISO and ASTM standards. 

If you have any questions about this or any of Epsilon's other products, please feel free to contact us.

All extensometers on this website can easily be shipped with the mating connector already installed, so you can plug into your existing electronics.  We stock connectors for every common brand of test machine.  To learn more about interfacing an extensometer to test equipment, click here.

High Performance Extensometers to Meet a Great Variety of Materials Testing Needs

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, 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.  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.
