BJ-X Portable metallographic microscopeDetailed product description：

Product Introduction
The BJ-X portable metallographic microscope, due to its built-in vertical illumination light source, can be easily used on site or when it is not possible to make samples to identify the microstructure of various metals and alloys. It can be widely used in factories and laboratories for casting quality identification, raw material inspection, or research and analysis of gold microstructure after material treatment. It can also be used as an antique gemstone and for surface fine observation.
