Introduction:

• JG-M200 transmission reflection upright metallographic microscope provides customers with cost-effective metallographic analysis and industrial testing solutions with excellent imaging system and comfortable operating experience. The structure adopts an observation tube with the best comfortable angle for newborn beds, which can alleviate the tension and fatigue of users under long-term working conditions and ensure the best observation state. The scale on the observation tube facilitates users to adjust the optimal pupillary distance range by themselves.

Encoding type objective lens converter	High precision internal positioning 5-hole bright field encoder converter with brightness memory function. The encoder type objective lens converter integrates the hardware settings of the microscope with the JG-M200 image measurement software. The magnification of the objective lens is displayed on the screen, and the calibration value recorded in the software can be automatically adjusted when switching magnification, eliminating measurement errors caused by forgetting to switch software magnification. The brightness memory function can remember the illumination brightness when using each objective lens, and automatically adjust the light intensity when different objectives are switched to each other, reducing visual fatigue and improving work efficiency.
