Abstract:
     The device, belonging to nondestructure measuring instruments, is comprised of a high power length measuring microscope, a reflector, a lifting mechanism, a transparent test tube shaft and an illuminating light. The reflector is glued to the lifting mechanism by 45 deg., and the oil seal overlaped on the transparent test tube shaft is refracted into the length measuring microscope, in which the dimension is observed with an error of one micrometer. The device can measure hugging contact width of several oil seal lips of same or different specifications simultaneously.
