No, it certainly should not be micron, which is not an SI unit. The symbol for micron is �, which is merely a prefix in the vocabulary of SI, in which the micron's replacement, micrometer (or micrometre), is �m.
Of course, one must acknowledge that many (if not most) engineers and others still use the term. Regarding the gadget, it's a matter of emphasis. The gadget, micrometer, has the emphasis on the second syllable, whereas the unit, micrometer (or micrometre), has the emphasis on the first and third syllables.
