Description

Technical Field

[0001] The present application relates to the technical field of surface parameter measurement, and in particular to a crucible roughness meter. Background Art

[0002] In chemical plant production, cylindrical boron nitride crucibles are often used. Due to process requirements, the inner surface of the crucible needs to meet the roughness requirements. Therefore, the inner wall of the crucible needs to be polished and the roughness of the inner wall needs to be measured before use to detect whether it reaches the required roughness.
