I am have recently learned that my analog hygrometer dial is more or less "frozen" for lack of a better term so I got a digital hygrometer on ebay. In an effort to get an accurate humidity reading I calibrated my hygrometer using the salt test and got a reading of 72% after letting it sit overnight, good enough as a minus three reading. So I put it onto the top shelf of my glass top humidor so it could be seen without opening the lid. After a couple days checked in and the reading was 84%. With my humidor having some Cigar Mechanic Beads and 2 water pillows, I took out the Cigar Mechanic Beads and left it to stabilize again overnight and the reading did not change. So I put the hygrometer in with my Cigar Mechanic Beads in a zip lock bag and the reading went up to 99% within an hour.

I guess my question is what should I do. How reliable is the salt test, is it possible my reading was way off? Any thoughts are appreciated!
