Product Description

The butterfly extensometer is mainly used to measure the mechanical properties of metallic materials and some non-metallic materials. It can be used with a universal testing machine to measure the displacement or strain of the material and the elastic mold and yield strength of the material can be obtained through conversion. And can be used for deformation measurement analysis and control of rebar tensioning process. Therefore,it is widely used in industrial displacement or strain measurement analysis and control. Especially the measurement of the mechanical properties of the screw steel is more superior.

Features

It has simple structure, convenient use, reliable work, good adaptability, economy and durability, and can be reused, and the measurement sensitivity can be improved by increasing the gauge distance.The instrument is light in weight, clear in reading, and compact in structure. A dial gauge or dial indicator can be selected according to different accuracy requirements.
