So i have two digital hygrometers that i have salt tested and neither has been on the money. I have a analog hygro that i have salt tested and it sat right at 75rh. I have some 65% heartfelt beads. When i put the analog in the humi it reads out a rock solid 65%. When i put the digital hygro's in they both read about 55%. The digital's are reading a perfect 70F, which that is the room temp that i keep the humi in. So to make a long story short, should i trust the beads and the analog or the digital hygros? I have heard how poor the analog hygros are so im a little afraid of having too low of rh, but with all the good reviews on the heartfelt beads, i feel i should trust them and my good ole analog hygro.Thanks for any help.
