DY-2 Butterfly-Type Extensometer

Overview

The butterfly-type extensometer is a mechanical contact-type displacement meter, and is made for measuring the displacement of materials, so as to obtain the indicators of certain mechanical properties.

It has a simple construction and is easy to use, reliable, highly adaptative, economical and durable and recyclable. In addition, the measurement sensitivity may be improved by enlarging the gauge length.

The device is light in weight, clear in scale and compact in structure, and dial gauge and dial indicator are optional according to different accuracy requirements. Therefore, it is a necessary and ideal device for material test.
