dial

A Mitutoyo ABSOLUTE Digimatic bore gauge designed exclusively for ID measurement. A minimum value holding function provides easy measurement of hole diameter. Up to three sets of master value and upper/lower tolerance values can be memorized and recalled at the push of a button. An analog bar indicator is integrated to enhance ease of reading, especially for GO/å±NG judgement. Measurements can be made inside very deep holes by using up to four extension rods.
