4XBmetallurgical microscope
■application
This instrument is used to identify and analyze the microstructure of various metals and alloys, and can be widely used in factories or laboratories for casting quality identification, raw material inspection, or research and analysis of metallographic structure after material processing. This instrument is an inverted metallographic microscope. As the observed surface of the sample coincides with the surface of the worktable, it is independent of the height of the sample, making it easy to use. The instrument has a compact structure and a beautiful appearance.
