Of course, I know that, no worries. But I was hoping something around d = 1 °C, I could have made use of it pretty easily for preliminary experiments before trying to get funds for better equipments, with guaranteed performance, and 0.1 < d < 0.01 °C (I don't need the latter, but only the most accurate devices may be reliable enough at the 0.1 resolution I need). For what I had in mind, extreme absolute accuracy is unnecessary. No Star Trek or lasers here. :]

But depending on the cost and progress, I may still want one Kimmoli. If not for science, just for nerdiness. I am going to monitor this thread.
