A Mechanical Extensometer is a precision instrument used to measure linear deformation, strain, and elongation of test specimens during tensile, compression, or flexural testing. It is directly mounted on the specimen gauge length and provides accurate displacement readings through a mechanical dial gauge or lever mechanism. The device is widely used in material testing laboratories, research centers, and quality control departments for metals, polymers, composites, and construction materials.
