Bore Gauge is the comparative measuring instrument which measures internal diameter of a hole by comparing with master gauge (micrometer, ring gauge etc.).
Center of prove and anvil are guided to diameter part of a hole by guide assembly and displacement of contact point is transferred to dial indicator
(Automatic centripetal mechanism ) by right angle change in the ratio of 1 : 1 with cam mechanism.
Measurement accuracy is changed according to graduation (resolution) of used dial indicator. Measuring range are available from minimum φ6mm to maximum
φ450mm according to size of diameter.
Bore Gauges

- Compliance with JIS B 7515A.
- Anvil and Contact point are using the carbide ball.
- The measuring depth can be extend using the extension rod to measure a deep hole.
