Re: Measuring humidity
This is the best one I have seen for the price.

It is a Mannix Model EMR963HG with a remote sensor. Cost about $80,
with central unit and remote.
Nothing at Radio Shack or local will come close. But if folks want to
run themselves ragged to save a couple of bucks, go to it!!

I've spent the morning searching for a hygrometer, and finally came
home with one that seems to work okay.
I found another Radio Shack I hadn't known about, and a very helpful
person inside (the other Radio Shacks couldn't tell me anything:
couldn't tell me if the item existed, if it was on order, if it had
come in, if they were ever likely to get it, if I could special
order it, didn't seem the least interested in helping me find a way
to obtain it) who looked it up online and said there's no such item
in Radio Shack's catalog. So maybe it's been dropped from their
inventory since all you guys bought yours.
She suggested I go to a large marine supply place, so I went there,
but they didn't have anything either. Again, there was a very
helpful person who was interested enough in my problem that she
called someone at their head office in Seattle, and after talking to
him a while called me over and said "I think he's got the answer for
you" and handed me the phone. The guy in Seattle said, "Here's what
you do. You take two thermometers, and you get the bulb of one of
them wet, and you put them in a sling thing and sling them around,
and then you take the difference in the temperatures." I said,
well, yes, I could do that I suppose, but I was hoping to find an
instrument that would do it for me. He said sorry, he'd never heard
of such a thing. (BTW, Camden, THAT's funny).
At any rate, I finally found a temperature-humidity thing at a
garden store for $34.99 (I had already exhausted all the hardware
stores and building supply places a couple of weeks ago) and have
been having fun taking it around to various places in the house and
outside.
Unlike the cheaper one I got, this one is very responsive, as Judy
said hers is. So far I have ascertained that the temperature and
humidity in the workroom are the same as the temperature and
humidity outside, which is what I would have expected with the room
wide open to the outdoors, and also within a couple of points of the
temperature and humidity at the airport. We're in our legendary
fall weather which is drier and warmer than the rest of the year;
this afternoon it's about 70 degrees and 64% humidity. So I still
don't know if it will measure accurately at more normal higher
humidity ranges, but so far so good.

Don,
I got the digital hygrometer with the remote sensor at Radio Shack.

The nicest hygrometers and most usefull ones are those that have a remote
unit...you can put the remote unit in a humidity chamber and set the other
unit elsewhere and monitor the humidity...they also have cumulutive
readouts, so you can get the average RH too.
Where did you get that?
I use a digital hydrometer that I purchased at Radio Shack but for more
accuracy I still use my wet/dry bulb thermometer.
