Ojiyas master gauges are used for comparative gauging as well as for checking, calibrating, or setting of gauges or other standards and maintaining comparator type of measuring instruments. For instance, cylinder gauges, bore gauges and air micrometers uses a master gauge for setting.
Ojiyas provides master gauges with high accuracy. These gauges undergo sub zero treatment to increase hardness, strength, wear resistance and dimensional stability. As a result, Ojiyas master gauges have improved lifetime and consistency.
