These are the 8 best out of 12 of the cheapo Amazon hygrometers. (should read 60% in the pic)
I've also done the salt slurry calibrate to 75% and mark the error on each with a piece of tape.
They're good enough for curing; I'm most concerned with the change in humidity rather than the value displayed.
