The Series MD dial type air gauge, 1 or 2 channel micrometer display, is a precision, non-contact measuring instrument when combined with a customized air probe sensor.

Air gauge measurement has been around for decades. It is a non-destructive testing method that utilizes air flow and the resistance created between an object under test and the air gauge’s sensing probe. The air resistance or back pressure changes with distance between the air probe and device under test. This air pressure change out of the air sensor can be scaled on a display to determine dimensional analysis as well as product acceptance.

The MD Series dial type air gauge micrometer with separate, customized air probe sensor performs fast, easy and precise dimensional analysis repetitively on components or subassemblies. Unique adjustment functions allow for accurate magnification tuning over a wide range. The MD’s are available in a single channel indicating the measurement of one part or a dual channel type which indicates the measurement of two parts at once providing a higher level of part pass/fail status.

The air gauge technology offers sufficient magnification and reliability to measure small tolerances down to 1 micron. High pressure air blows off dust, oil, etc. to ensure accurate measurement
and a quick response. Due to its fast response, outstanding tolerance and accurate repeatability, Tosok air gauge micrometers are ideal for quality measurements on the production floor or in
the lab.
