Metallographic microscope DMI20
The DMI20 metallographic microscope is used to identify and analyze the microstructure of various metals, alloy materials, and non-metallic materials, and is widely used in factories or laboratories for raw material inspection; Quality assessment of castings or metallographic structure analysis after material treatment; As well as conducting research on surface phenomena such as surface cracks and spraying, the metallographic microscope DMI20 is used for metallographic analysis of steel, non-ferrous metal materials, castings, and coatings; Petrographic analysis in geology; And an effective means of conducting microscopic research on compounds and ceramics in the industrial field.

Professional quantitative metallographic image analysis system, capable of real-time research and analysis of metallographic spectra, such as grain size measurement and grading; Measurement and rating of non-metallic inclusions; Measurement and rating of pearlite and ferrite content; Measurement and rating of graphite spheroidization rate of ductile iron; Analysis and statistics of decarburization layer, carburization layer measurement, surface coating thickness measurement, etc. This includes functions such as image acquisition, storage and display, image enhancement, image segmentation and morphological processing, geometric parameter measurement, image scratch processing, annotation, stitching, depth of field overlay, photo fixed magnification printing, report design, etc.
