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.

Sometimes things break, need new batteries, etc....I don't see where in the recommendation it implies that the need to recalibrate happens "often".

If your Rh was reading 65% steadily for a year, and suddenly was at 53%, it is wise to recalibrate your hygrometer to see if it is just "off", or if you do in fact have a much bigger problem with your humidor.
