It is a precision instrument employed to compare the dimension of a given component with a working standard (generally slip gauges). It does not measure the actual dimension but indicates how much it differs from the basic dimension (working standard). Uses of Comparator:   For calibrating the working gauges   Used as working gauges   Used as final inspection gauges Essential characteristics of a good Comparator:   Robust design and construction…
