This "ultra large diameter gage and setting master series" was developed to measure part sizes beyond those of the Dorsey Metrology traditional large diameter gage family. The ultra large series measures large parts in the range from 60", 1500mm to 240", 6000mm. These instruments are designed to be accurate, rigid, stable, lightweight and durable.
The Gage Check is a multi-axis metrology display that accepts up to eight discrete inputs. It features intuitive visual displays, helpful audio cues and user-defined formulas. It also reports dynamic min/max measurements, provides SPC analysis from an integrated database and includes connectivity to PCs and other peripherals.
