Air Gaging technology is a highly reliable method for many applications in industries where a high volume of parts is produced or where the precision of hard-to-access dimensions makes other measuring techniques impossible. Because air gaging is a non-contact method, it is useful for measuring soft, highly polished, thin walled and other materials susceptible to marking. Air gaging is extremely easy to use and requires no special skills for the operator. Multiple operators will achieve the same or nearly the same measuring results when measuring the same part, thus taking operator technique out of the measurement results. This is a problem when you're using a contact gage.
