The product name of the right angle level ruler is also known as the right angle level ruler, right angle ruler, vertical level ruler, cast iron vertical level ruler, right angle guiding ruler, 90 ° angle ruler. The right angle level ruler is suitable for high-precision mechanical and instrument inspection, as well as inspection of non perpendicularity between machine tools. It is an important measuring tool in the mechanical industry for installation, processing, positioning, marking, etc. Its characteristics are high precision, good stability, and easy maintenance.

The right angle ruler is manufactured according to the GB6092-85 standard and made of HT200 material. It is mainly used for inspecting and marking the right angle of workpieces. When installing and repairing equipment, it is used to inspect the verticality of the relevant surfaces of parts or components. When installing and repairing equipment, a right angle ruler is used to check the perpendicularity of the relevant surfaces of parts or components.

A measuring instrument, also known as a 90 ° angle ruler, used to check the errors of right angle, perpendicularity, and parallelism when the measuring surface and base surface are perpendicular to each other.

Granite square ruler, also known as marble square ruler or rock square ruler. Mainly used for measuring the flatness, perpendicularity, and straightness of workpieces. The main mineral components of granite angle rulers are escape stones, plagioclase, a small amount of olivine, biotite, and trace amounts of magnetite. They have a black color and precise structure. After billions of years of aging, their texture is uniform, stable, strong, and hard, and they can maintain high precision under heavy loads. Suitable for industrial production and laboratory measurement work. Characteristics and advantages of granite angle ruler:

1. After long-term aging, the rock has a uniform organizational structure, linear expansion coefficient, disappearance of internal stress, and no deformation, resulting in high accuracy.

2. Good rigidity, high hardness, and strength.

3. Not afraid of acid and alkaline liquid erosion, will not rust, does not need to be coated with oil, is not easy to stick to dust, easy to maintain, and has a long service life.

4. No scratches, not hindered by constant temperature conditions, and able to maintain temperature measurement accuracy at room temperature.

5. Granite and marble square rulers are not magnetized, and can move smoothly during measurement without any sense of stagnation, unaffected by moisture, and have good plane accuracy.
