• In coordination with the max./min. masters and the customized air probe sensor, air adjustment knobs enable accurate setting of the zero and full scale on the dial
• Non-contact measurement eliminates the potential for damage to the test part
• No Power Required; Simply connect compressed air line
• Pressurized air from the sensor cleans off oil and dust on the test pieces, assuring accurate measurement
• Simplified operation and setup compared with digital models

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 the distance between the air probe and the 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 MDs are available in a single channel indicating the measurement of one part of 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 the dust, oil, etc. to ensure accurate measurement and 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.
