My hyrgometer seems to be off about 4%. I did the salt test and after 12 hours it read 71rh. I am off about 4%. I understand that when I put the hygromter in my humi, I have to add 4% to the reading to get the acual humidity level. (if it reads 70 in my humi, it's actually 74)
If I switch to beads, I dont have to recalibrate do I? I am assuming the salt test works the same for all humidication devices.
Also I was looking at the 65% bead disc. I am assuming I just have to add water that's it? Do I have to do anything else?
