This apparatus is used to verify the dimensional and shape tolerances of rock core specimens of up to 75 mm diameter by 120 mm long. The straightness of the cylindrical surface, flatness and verticality of end surfaces can be verified by the same dial gauge using the magnetic holder in the desired position.
The apparatus consists of:
- 85 x 85 x 250 mm V block
- 25.4 mm x 0.001 mm digital gauge with magnetic holder
- Additional platen 100x180x8 mm
- 6 magnets for core locking
Support surface is not included in the apparatus
