These are very cool and an excellent weapon to have at your side when you're meeting with administration and the folks from facilities. It is one thing to complain to them about humidity swings but to show them accurate graphs with the facts right there in color is very powerful. My problem is that all of these data loggers are for windows software. Does anyone out there know of a decent data logger that is compatible with Mac? The last time I did this I had to get a old windows computer from surplus and run all of that separate. Everything in this building is Mac and it's a royal pain to go back and forth.
