Thought these were reading very low in the humidor so I put them in a sealed container with 14 Boveda 65%rh packets (that’s just what’s in there I didn’t choose 14 for any reason). Not only is the rh no longer within the +/-2% rh tolerance but the thermometer (which is much easier to be accurate with) is wrong.They’re ok for a couple years but be ready and willing to throw them out.
