I'll have pictures next month...doing a 5 day study with two of them.

They're wanting to test the one-hour warm up, and calibrations at only 24/48/72 hour intervals. I don't know if it'll be the same sensors as are on the market now, but I'd assume they are...?
I also won't know the data until the study is wrapped up, so I won't be able to tell you all the accuracy until I get my "results" back in the mail.
