Precision two-point dial bore gauge with spring-loaded centring disc. Lighter, stable version with CRP elements, hence reduced thermal expansion and increased corrosion protection. Hand heat insulation on the frame additionally reduces the effects of temperature. Smooth and precise transmission of the contact point travel by a curved segment. Fixed contact point with hardened steel ball allows adjustment to different ⌀.
For precise measuring of bores in terms of ⌀, roundness, and cylindricity as well as measurements of internal profiles.
Precision bore gauge complete in a wooden case (without dial indicator).
Precision dial comparator No. 434674, inductive precision dial comparator No. 434670, dial indicator with anticlockwise scale 434807 size 10, digital dial indicator 434322, setting rings No. 484030.
When using precision dial indicators, an additional extension No. 434920 size 10 or contact point No. 434900 size 16 is required.
