Air micrometer is a precision comparator type measuring instrument that employs air flow volumes and air pressure to determine the size of measured part dimensions. Operation is non-contact and is as simple as presenting a tool to a work piece and observing a reading. Furthermore, using air micrometer will not damage the surface of the measured parts. A row of multiple column can be used for measuring several measuring points in one glance that can reduce measurement times. The benefit of air gauging is its ease of use, which produces accurate results even when used by unskilled operators.
