Something like the Jones and Lamson/Hartness Optical Thread Comparator? Invented in 1920. J&L Optical is still in business in Springfield Vermont and there are probably close to a million of their comparators out there.

A "Universal Metroscope" ?
Is there some reason they don't call it what everyone else seems to call it... A ULM. (Universal Length Measuring Machine)?
In any case, I've never seen either and have no idea how either machine works... on in the case of the Chinese machine how it most likely doesn't work much like OneCNC doesn't work very well. :P

A Metroscope is exactly the device most often used to check thread plug gauges in at least most UK Calibration Labs, except Carl Zeiss machines are more generally seen.

They even publish their prices for checking and/or certifying plug and ring gages.
