So far I have bought 6 hygrometers, the round ones, from Amazon to use in dry boxes but all of them count down 23%, 22%, 21%, 20%, 10%. I’ve seen you tube videos and images in the AMS pods make for example where the meters are displaying the steps between 10% and 20%. Rather than randomly buying for all the suppliers on Amazon or elsewhere does anyone have a link to one that works?
