Default Re: Beginner Questions (Ask Them Here!)

I keep reading about hygrometers having to be recalibrated. Some recommend to recalibrate after a sudden change in Rh.
Isn't the point of this tool to accurately indicate the rh of a given space? How accurate is it really, if one can't trust it and has to recalibrate it so often?

Thanks.
