Testing Hygrometer with salt&H20

[Roham]

Thank you, but I already read those links

I was wondering what makes it an accurate method.... How is it that exactly 75% humidity is achieved with a salt water mix?

I found this site which goes into NaCl (sodium chloride or simply, salt): http://www.tis-gdv.de/tis_e/ware/gewuerze/salz/salz.htm

Apparently at 75% relative humidity, NaCl crystals begin to disolve. Thus, by adding water to NaCl to its saturation point, you are basically replicating this in a controlled environment allowing you to properly calibrate your hygrometer.

I found an answer to my own question too:) Thanks Hex.

Here is another link if anyone is interested...

It's a cigar FAQ, it even has a vesion you can download to your palm.

This is where the info on salt letting off 75% humidity is.

thanks for that link....just downloaded that to my palm.
