Extensometers provide high-resolution 1D strain measurements during mechanical testing. These measurements are necessary for accurate determination of material stiffness and strain-controlled testing. Special extensometers are used for internal (e.g., environmental chamber) and external (e.g., induction furnace) high-temperature testing.
