Im a big fan of my Xikar! Cost me 30 bones but it comes with a lifetime guarantee. Its a digital display with Temp and RH only. Its not able to be calibrated, but comes calibrated out of the box. Not sure how that works and what not, but Ive not had any problems (That I know of. Hmmm....Maybe I have and just don't know it.) I have had some people say they didn't like that type of hygrometer just because they can't be calibrated.
The way I see it is, if Xikar didn't know what they were doing they would be "calibrateable". <---(Is that a word?
) They've gotta be doing something correct.
