DY-GT1 Measuring Device for Steel Ruler

◇ Product Introduction ◇ Product Features◇ Technical Indicator

[Product Introduction]

DY-GT1 steel ruler verification device (verification of 1-meter steel ruler) is designed and developed according to the current JJG1-1999 steel ruler verification regulations.

The verification device can be used to verify the steel ruler;

It is a precision written metal ruler with a 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 steel ruler verification device adopts laser marking, marking readings and patterns, integrating modern science and technology and full automatic manufacturing technology of 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.

[Product Features]

1. There shall be no scratches, bumps, rust and other phenomena on the engraved line surface of the third-grade line grain ruler.

Carving line should be uniform, perpendicular to the ruler and extend to the ruler, no broken line, heavy line phenomenon.

2, in the verification state, through the reading microscope observation, the whole line should be clear.

3, three equal line grain ruler ruler digital size should be moderate, can not affect the line, and consistent.

4, three line grain ruler accessories (thermometer, magnifying glass) should be complete, the magnifying glass should be clear imaging and sliding on the guide rail flexible.

5. At the beginning of the verification, the third-grade line ruler should meet the above requirements, and the appearance defects that do not affect the metering performance are allowed in the subsequent verification and inspection in use.

6, marking for the new system of three line grain ruler, on the ruler back flange should be marked with manufacturing materials, factory or factory mark, factory number;

The name and system of the measuring instrument should be marked on the measuring box.

7. Two copies of the equipment instruction manual, one copy of the product certificate, one copy of the packing single, and each part contains the verification certificate.
