Can someone bring me up-to-speed about HOBO hygrothermographs?  We 
don't use these at the Phillips Collection, but I know other museums use 
them.  Are these more accurate than the paper recording units?  Is it correct 
that you don't have to calibrate them monthly?  How often do you have to 
calibrate them?  Thanks.
