Calibration of a Hygrometer...would this work

But you have to leave it for the full 24-36 hours, after 7-8 hours it is still all over the place.

I am not sure I would trust the larger packets though as the kit uses a really small volume. Also, if you have the smaller 69% packets they use for shipping, I would not trust those as they dry out really quickly.

Aaron, just out of curiosity, did you ever cross-check any of those hydrometers with a salt test?

Reason I'm asking is that they do appear to have the ability to determine the accuracy of the packs after manufacturing and mark them. I have a number of packs that came out of Fuente boxes and the packs have their specific RHs printed on them. I don't recall seeing this level of detail on the larger over the counter boveda packs. So, I'm wondering if they might shuttle the more accurate packs over to the hygrometer calibration kits.
