The standard gauge equipment (also known as the dotting machine) is designed and manufactured according to the requirements of the standard ISO 6892 metal material tensile test, the equipment is used to dotted and distanced on the tensile test specimen, easy to operate. It is a supporting instrument that should be prepared in the laboratory.

Working principle: The dvice rotates 360° through an axis with a spiral belt, lifts the punch sequentially at different angles, and strikes the dots with the help of the spring's elastic sequence. The handle can be shaken for one week to punch an accurate specimen with a straight line arrangement of 10 mm and a total of 41 points (total length 10 mm X (41-1) = 400 mm) on the sample blank.
