Abstract
A height gage having a cylindrical column supporting a slider vertically movably thereon. The slider vertically movable to the column is restricted from rotation by a scale vertically extended along the column and the slider is connected by way of string members to a balance weight provided in the column so as to facilitate the slider operation. Air jetting ports are formed to the bottom surface of a base having the column erected upright thereon, so as to form a pneumatic bearing between the base and the substrate for mounting the height gage to facilitate gage movement.
