Brief introduction:
BJ-X portable metallographic microscope, with its built-in vertical lighting system, can be used conveniently for on-site identification of different metal and alloy structures , especially when specimen manufacture is not available. It can be widely employed in factories and labs for the metal quality identification, raw material inspection, and metallurgical structure analysis of metal pieces after treatment, as well as for observation of fine surface structure of antiques and jades.
