nope as long as its german made O.O
but most refractometers should be like +/- .00001 or something like that. +/- .0005 should be good enough....
at my LFS there was a refractometer going for $11 or was it $110...couldnt really see it cuz the back was so dark and i was in a hurry. going to check that out 2morrow (dont think its $11 unless its seriously used....)
