It's actually really hard to imagine an actual physical apparatus for producing a "reference" Kg mass using the new definition of Kg.
I get the feeling this just changes the definition of "Kg", but not how reference Kg's are actually produced?

If there wasn't one, it wouldn't have changed. But it's fit for measuring micrograms up to grams. One won't measure actual kg on it, at least not currently.
