That is the one I have, does anyone know if it is pretty accurate. I am calibrating it and have read that you put some salt in a bottle top then add some water (just enough to get it wet) then wait about 6 hours in a tuperware container. It should then read 75%. Is this the right steps or is there an easier way?
Thanks
Oh incase it is confusing I have the digital one, not the humidor one that this post was originally about.
