An air surface gauge stand of a type adapted to support an electronic measuring head or similar device for movement above a horizontal reference surface. The device includes a lower base having hollow feet to which a continuous supply of low pressure compressed air is fed to permit the lower base to be easily slid over the reference surface. An upper base is supported upon said lower base at points directly above the hollow feet in such manner that the upper platform is tiltably adjustable with respect to the lower platform about a substantially horizontal axis. A vertical supporting column extends from said upper base which supports a sliding clamp upon which the measuring instrument is mounted, the tiltable adjustment being employed to provide movement of the instrument relative to the lower base in which the vertical component thereof is extremely fine.
