Hygrometer

[Greg Newell]

Terry,
         Glad to see your still in the thick of it. I've been stumbling a 
bit in my own efforts of late. I'm spending a great deal of time trying to 
get my house ready to sell. I'm not sure I'll be moving but i have found a 
possibility that I just can't afford to ignore. Most all our efforts are 
going in that direction right now.
         Any idea where I could find one of these charts? Seems that Dave 
Porritt's gauge looks pretty good for the task. I like the idea of the air 
fully circulating around the board and therefore will have to build a hot 
box. Where do you keep yours? I've been daydreaming of hanging it from the 
ceiling vented above. Any thoughts?
