What is ring gauge
Circular gauge is made with specific size and durable materials havingcertain inside diameter tolerance.
Size and actual measuring value are engraved on master ring gauge.
Nominal size
Generally called size.Measured value
Size +/- tolerance value.
The main purpose of ring gauge is used as
inside diameter standard for comparision
measuring instrument.
(Ex):Inside diameter measuring tool (Three point internal micro, air micrometer...) is used
as a standard meter of zero adjustment.
