I figured I'd check both my hygometers. It has been almost 3 months since I last did it. I used the salt test and to my surprise the analog was dead on the mark at 75%. The digital was reading 73%. Go figure.

most digitals vary from 3-5%. If its only off by 2 thats pretty good...

I'm not complaining, I'm just surprised the analog was at 75% after not having calibrated it for 3 months or so.

I've heard that analogs are more accurate than digitals - all I've ever used is analog...

.. and the 'sheep method', of course - when the wool gets damp, it's too humid....
