4XB Binocular metallographic microscope Features: 4XB binocular-type inverted metallurgical microscope is used for the identification and analysis of various metals and alloys of the organizational structure, the general microstructure of the research work for the material after heat treatment. Microscope imaging is clear, of broad vision; the overall design is in line with the man-machine functions, fit to being operated for a long time. Can be widely used in factories or laboratories for the identification of casting quality. Raw material inspection or the treated material microstructure research and analysis work.
