Testing the humidistat

[mkeawsh]

Weeks ago there were directions on how to test to see if the humidstat was registering correctly with uniodized salt in a plastic bag. I am going to be starting up my bators again and want to do this. What is the link on BYC that I saw that?

Here is a how to calibrate
you can put the hygrometer in a sealed ziplock bag along with an open container of wet salt (consistency of wet sand, they say). After 6 hours, the humidity should read 75%. Again, adjust accordingly.
or you can do a search on BYC site to seee other ways.

Here is the most detailed explanation of calibrating a hygrometer that I've found: http://ezinearticles.com/?Prevent-Mold!-Hygrometer-Calibration&id=602308

I don't use all of the salts. Just plain old sodium chloride (table salt) since it's good enough for egg incubation.
