Epsilon Tech: All About Service

All Epsilon products come with a full, one year warranty. The warranty covers defects in materials or workmanship for a full year, excluding normal wear and damage from excessive applied force or misuse. Our full warranty can be found at the bottom of this page. Each unit is produced under stringent quality standards and is fully tested and calibrated before leaving the factory.

Certain items such as knife edges and ceramic rods wear under normal use, and a spare set is included. The modular design of the extensometers allows for easy replacement of damaged parts.


If you are having problems with any of the following issues and your extensometer is not visibly damaged, please contact Epsilon Technical Support using the link below before sending the unit in for repair. Troubleshooting issues are more easily resolved if you have the device in your possession.

  • Calibration process (cannot calibrate, error messages, etc.)
  • Measurement errors (noise, drift, incorrect values, etc.)
  • Strain control (cannot test in strain control)
  • Cyclic testing (problems during cyclic testing)
  • Installation / Initial setup

RMA for repairs or recalibrations

If your unit is in need of service, calibration or repair, please use the link below to initiate the RMA process. Once you have submitted the form, send your unit to our factory for evaluation and one of our representatives will contact you with a quotation for repair. If your unit is under warranty, you will not receive a repair quotation and we will return your repaired unit as soon as possible. Epsilon maintains a policy of quick response to keep your test lab running.

Our Warranty

1. Limited Warranty
Epsilon warrants all products of our manufacture (“Products”) to be free of defects in materials or workmanship for a period of 1 year from date of shipment. This warranty covers both parts and labor. Epsilon reserves the right to determine if defects are covered by warranty. This warranty does not cover items subject to wear. Specifically, this does not cover knife edges or ceramic rods. Upon return of item (shipping prepaid) for repair, Epsilon will determine whether the item is covered by warranty, and repair or replace it at our option.

The warranty period for any product is not extended from its original date by virtue of having been repaired or replaced under the original warranty.

2. Other Limits
THE FOREGOING IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. Epsilon does not warrant against damages or defects arising out of improper or abnormal use or handling of the Products; against defects or damages arising from improper installation (where installation is by persons other than Epsilon), against defects in products or components not manufactured by Epsilon, or against damages resulting from such non-Epsilon made products or components. Epsilon passes on to Buyer the warranty it received (if any) from the maker thereof of such non-Epsilon made products or components. This warranty also does not apply to products upon which repairs have been effected or attempted by persons other than pursuant to written authorization by Epsilon.

3. Exclusive Obligation
THIS WARRANTY IS EXCLUSIVE. The sole and exclusive obligation of Epsilon shall be to repair or replace the defective products in the manner and for the period provided above. Epsilon shall not have any other obligation with respect to the products or any part thereof, whether based on contract, tort, strict liability or otherwise. Under no circumstances, whether based on this Limited Warranty or otherwise, shall Epsilon be liable for incidental, special, or consequential damages.

4. Other Statements
Epsilon’s employees or representatives’ ORAL OR OTHER WRITTEN STATEMENTS DO NOT CONSTITUTE WARRANTIES, shall not be relied upon by Buyer, and are not a part of the contract for sale or this limited warranty, unless agreed to in writing by a corporate officer of Epsilon.

5. Entire Obligation
This Limited Warranty states the entire obligation of Epsilon with respect to the Products. If any part of this Limited Warranty is determined to be void or illegal, the remainder shall remain in full force and effect.
