Granite rulers are mainly used to measure the flatness and straightness of machine tool tables, guide rails and precision working surfaces. S&P Measuring Tool Granite Inspection Ruler is made of natural granite stone. It is an ideal reference level for the inspection of instruments, precision tools, and mechanical parts, especially for high-precision measurement.
· Ultra-precise standard that enables high accuracy measurement of straightness, perpendicularity, etc. 
· A product developed with "1 μm precision" as the core concept, allowing the ideal option to be selected to suit the usage and application.
· It could be as a master for shaft straightness inspection of various machine tools, such as semiconductor related equipment, inspection equipment, etc.
· It could be as a straightness reference when assembling and adjusting each shaft.
· It could be as an inspection master reference for machinery components.
· The usage side features a precision lapped finish.
· The precision surface is 1 face only.
