[Product Introduction]

DY-SDJ Grade III Metallic Wire Ruler is a precision engraved metal ruler with reading glass and thermometer.

In the surveying and mapping operation, it is often used to check the distance between map outline point, control point and coordinate dot, and it is stipulated in the national leveling specification as standard ruler to verify leveling ruler.

Other specialized departments are also widely used for measurement and metering of linear distances and marking.

As a high-tech and innovative new product of the 21st century with Chinese independent intellectual property rights, the third-grade metal wire gauge adopts laser engraving marking lines, marking readings and patterns, with the combination of modern science and technology and full automatic manufacturing technology of the machining center.

Products with high precision, high stability, high resolution, accurate to line width, engraved line spacing is consistent, differential linear rule curve of lift, no kick, peak valley accidental error values, vertical scribed line standard, feet good stiffness, deformation rate is low, good flatness, the precision indexes sharply higher than 2005 JJG71-2005 standard, has the world advanced level.
