The function and advantages of granite detection platform

Granite testing platform features and advantages:
        1: long-term natural aging, the structure of the rock even a small linear expansion coefficient, the internal stress completely disappeared, no deformation, so the measurement accuracy is high.
        2: good rigidity, high hardness, wear resistance.
        3: not afraid of acid, alkaline liquid material erosion, not rust, not oil, easy to sticky dust, maintenance, easy maintenance simple, long service life.
        4: no scratches, not subject to constant temperature conditions, at room temperature can maintain the accuracy of the amount.
        5: no magnetization, measurement can be smooth to move, no stagnation, not affected by moisture, the plane called good.
