Series Details
The RP series is a replaceable limit plug gauge that uses ceramics (zirconia). When frequently used sizes need to be replaced due to wear, or when a special size is required, it is an economical limit plug gauge in which only the gauge part can be purchased and the handle can be used as is.
~Example of using plug gauges to judge pass/fail~
- If you get GO and no NG, you pass.
