psychrometer chart

[Don]

Hi, 

One more good site with a calculator for those near sea level.

http://www.natmus.dk/cons/tp/atmcalc/atmoclc1.htm

and another explaining in great detail the formula(s)

http://www.faqs.org/faqs/meteorology/temp-dewpoint/

and another explaining cautions about using good psychrometers.

This quote is cute!

And note that humidity measurements never are terribly accurate, 2% error
in absolute hum. are pretty good, depending on where you are in terms of
temp and water content. Anything that reads "relative humidity=52.783 %" is
guessing (if you paid less than 100k$...:-)
