ABSTRACT:
The extensometer has first and second gripping portions on spaced members designed to be applied to a specimen by using only one hand. Changes in the length of the specimen are indicated by an electrical signal derived from a flexure strain gage arrangement in one of the members against which a probe is urged by forces on the other member. The coupling of the probe to the other member is through a spring biasing arrangement such that the biasing force can be changed so that the strain gage flexure movements can be made constant for different percentage elongations to be measured.
