Granite/Dolomite Micrometer is mainly used for high-precision parallel and flatness measurements of precision components.

The granite micrometer boasts high precision, rust-proof, non-magnetic, non-deformable, and excellent wear resistance.

Maintains stability under heavy loads, with a dense and uniformly textured structure.

The smooth marble micrometer is primarily used for high-precision parallel and plane measurements of precision components.

The smooth granite micrometer offers high precision, rustproof, non-magnetic, non-deformable, and excellent wear resistance.

The smooth micrometer gauge is crafted from high-quality "China Green" granite, machine-finished and hand-polished.

The smooth micrometer maintains stability under heavy loads and features a precise and uniform structure.

The granite micrometer screw gauge is primarily used for high-precision parallel and plane measurements of precision components.

The spiral micrometer features high precision, corrosion resistance, non-magnetization, non-deformation, and excellent wear resistance.

The marble micrometer features "China Green" granite material, processed through mechanical means and hand-finished.
