20x Metallurgical Optical Microscope Portable Measuring Microscope
A13.2502A13.2502 Portable Measuring Microscope, is designed to quickly
measuring the diameter of power particle, hardness test spot
diameter or thickness of coating layer. It is small and simple
design but very useful for outdoor work with LED light and small
size. It can be used for biology medicine agriculture and industry
area widely. It is the ideal instrument in medical treatment,
teaching demonstration and scientific research.

--Fixed Micrometer With Main Scale In Eyepiece : 0~8mm
--Moving Micrometer With Corss & Double Lines, Moved By
Measuring Knob The Fixed Micrometer has a main scale 0~8mm length, which is used
to fix the measurement position. When you turn the Measuring Knob,
it will move the Moving Micrometer and show its moving distance on
the knob by 0.01mm division. Keep record of its moving distance, it
will be the length you need to measure. | | Operation Manual | Measuring Diameter Of Power Particle (See Picture)
1. Put the microscope on the surface of objects, turn on the LED
light.
2, Adjust eyepiece (2) to see both micrometer clearly in view
field.
3. Adjust focusing ring (7) to see objects clearly in view field.
4. Fix the focusing by screw (9).
5. Turn Measuring Knob to move the micrometer, until the cross
center locate on left side of the particle. Read out the main scale
as 5 and measuring knob scale as 0.36 (a). (Left Picture)
6. Turn Measuring Knob to move the micrometer, locate the cross
center on right side of the particle. Read out the main scale as 4
and measuring knob scale as 0.51 (b). (Right Picture)
7. Moving distance (Y) is the difference between (a) and (b)
divided by objective magnification (X) : Y=(b-a)/X.
8. Measured Diameter = Moving Distance = (5.36mm-4.51mm)/1X=0.85mm |
