hygrometers

Wondering if anyone else is having bad luck with those little hygrometers. They're black, about 1"x2", 2 batteries, and the humidity numbers seem to be way off.

There are a few methods of calibrating hydrometers but I use 2 of the cheap digital meters in my coolidors. I figure if they are reading within a couple of points of each other they’re accurate enough.

Thanks, from Norco, CA. I'm finding (or I suspect) mine are way off, not just a few points. I dunno!
