4XB Metallurgical Microscope
1 . Applications & features:
1. Used to identify and analyze the organizational structure of all
kinds of metals and alloy materials.
can be widely used in factories and laboratories to verify the
quality of casting, to inspect the raw material and analyze the
metallographic organization of material after treatment, and to do
some research work for surface spraying etc.
2. It is a binocular-type inverted metallographic microscope
3. It can be equipped with photographic device to proceed
photomicrography.
4. Due to the surface of specimen to be observed coinciding with
the table surface, it has no limit to the height of specimen.
5. The equipment base has large supporting area and the arm bend is
strong which makes the gravity of equipment lower, thus it can be
placed stably and reliably.
6. There is a 45 º tilt angle between the eyepiece and supporting
surface, and this make it comfortable to observe.
7. It features convenient operation, compact structure and elegant
appearance.
