Bore Gauge

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 Q6mm to maximum Φ450mm according to size of diameter.
