Precision Granite Measuring Tools Granite Lab Tables
Precision Granite surface plates are manufactured to meet or exceed the tolerances specified by Federal Specification GGG-P-463c. A Precision Granite calibration certificate is included with every surface plate, guaranteeing overall surface flatness and repetitive gage measurements and is traceable to N.I.S.T. or equivalent National or International Organizations. Long-form certification is also available.
These plates are made of black granite which is stronger, denser and more stable than light colored granite. The granite properties determine the stiffness of the granite so accuracy can be guaranteed with less thickness than other types of granite. This translates to less freight and handling whenever the plate is shipped or moved.
