extensometer

[‚ek‚sten′säm·əd·ər]
(engineering)
A strainometer that measures the change in distance between two reference points separated 60-90 feet (20-30 meters) or more; used in studies of displacements due to seismic activities.
An instrument designed to measure minute deformations of small objects subjected to stress.
