Butterfly extensometer is mainly used to measuring some nonmetal material’s mechanical propertie. Can measure material’s displacement and strain with universal testing machine, and material’s elastic mould and yield strength can be obtained by conversion. And can be used for deformation control of rebar drawing process. Butterfly extensometer can be used in indoor or outdoor. need not revise.So it is widely used for analysing and controlling industrial displacement or strain,specially for measuring mechanical property of twisted steel
