Texas Measurements, Inc. --YEF/YF Series

YEF/YF Series
Post-yield Gage

This gage features a special plastic carrier backing capable of withstanding extreme elongation without creeping or cracking. The YEF is available for 10%-15%, and YF for 15%-20% with high accuracy. These gages must be bonded with CN or CN-Y adhesive.
