COMPARATORS

Page 2: comparators

(i) In mass production, where components are to be checked  at a very fast rate.

(ii) As laboratory standards from which working or inspection gauges are set and correlated.

(iii) For inspecting newly purchased gauges.(iv) Attached with some machines, comparators can be 

used as working gauges to prevent work spoilage and to maintain required tolerances at all stages of manufacturing.

(v) In selective assembly of parts, where parts are graded in three or more groups depending upon their tolerances.
