The Mitutoyo 900581 center master attachment for inch-measuring height gauges supports measurement of center-to-center distance between holes in a workpiece. The attachment replaces the scriber or electronic probe. The 900581 is an accessory for use with a Mitutoyo inch-measuring height gauge, which is used to measure and/or mark vertical distance from the base of the object in fine units.
The attachment has a triangle shape, with a point to insert into the hole of a workpiece to accurately measure the vertical distance of the center of the hole from the base of the object. The attachment can be used with hole diameters from 0.04 to 1.5 inches.
Mitutoyo manufactures precision measuring tools, metrology equipment, and systems. The company was founded in Tokyo in 1934 and formed Mitutoyo America Corporation in 1963, which is headquartered in Aurora, IL.
