ABSTRACT:
A gauge for indicating measurements including a dial plate provided with measurement scales, a central rotating shaft and an indicating plate. The dial plate is disposed in front of the indicating plate, with an arcuate slot opening formed in the dial plate so that a corresponding arcuate colored band provided on the indicating plate may be seen through the opening for unobstructed viewing of measured results as the indicating plate is driven by the shaft. The indicating plate may also be provided with an indicator which extends through the opening to prevent obstruction of the measurement scales during use.
