I wrote down how to calibrate a hygrometer from a thread here on BYC. I haven't tried it yet, but here it is.

1/2 cup salt
1/4 cup water

Mix in a bowl. Put bowl in a ziplock bag with the hygrometer in the bag also. After at least 8 hours, it should read 75 %.

(Make a wet sand mixture of the salt and water. Not too soupy.)

Hope this helps.

To check thermometer accuracy:

I've heard you can put them in ziploc bags and then imerse them in the ice/water mix. I guess it's up to you on whether or not you trust the bags.
