With default data acquisition hardware settings, no calibration (just going from the specs), and no attempt at doing anything to smooth things out, this is my first attempt at capturing degree of roast data in Typica. Apparently when the measured values are out of range on the high end the signal drops out on the bottom (I need to verify that and make sure it's not a bug in my software). It's a noisier signal than I'd like, but I've got some tricks that might help with that. Still promising tech
Here are the graphs. B-1 has a 15.71% mass loss and the ground coffee measures 53.7 on the Agtron gourmet scale. B-2 has a slightly higher 15.86% mass loss and a slightly lighter 53.9 degree of roast. Those post-roast measurements are closer than some roasters get trying to follow the same plan but these are clearly very different roasts.
