リングゲージの校正方法 | オーエスジー

Your threaded ring gauge (GR) is calibrated with a wear inspection plug gauge (GW) for threaded thread ring gauges.

OSG handles wear inspection screw gauges in standard stock.

In addition, we also accept the service of sending the actual gauge and calibrating it.

* In the inspection report at the time of ring gauge calibration, the number of the wear inspection plug gauge that inspects the ring gauge is listed. Calibration certificates and traceability certificates can also be issued. (Charged)

In addition, we sometimes receive questions about whether plug gauges such as GP, IP, and WP can be used to calibrate ring gauges such as GR, but they cannot be used for calibration because they are used for different purposes.
Also, please note that it is not possible to make it possible to use something that has been rejected in the calibration process again.
