YF series Post-yield strain gauge
This gauge is designed for measurement of large strain up to 15 to 20%. It is not applicable to the measurement of repeated strain either in elastic nor in large range. The CN-Y is recommended as an adhesive if the measurement is made after a few days or longer of strain gauge bonding. Large strain measurement is possible even after one year of bonding the gauge with the CN-Y adhesive. (Provided that the specimen is stored in room temperature.)
