Hi Tom, Here at Dampp-Chaser we use the Onset HOBO U12-011. Onsetcomp.com We've used these for about ten years. We have been able to characterize their drift over time and don't have to send them back for recalibration since we know how they perform. Roger Roger Wheelock, VP Dampp-Chaser Corp.

I'm searching for one that will log both T and H every 60 seconds or so - 65K+ data points - with an accuracy of +/- 1 or 2%. It should be able to interface with a desktop or laptop computer (XP operating system). Any suggestions?
