Emissivity of 1 means the power is lowest. As emissivity declines toward zero, power increases.
The IR camera software computes temperature based on the emissivity you enter into the software. In the second test, they entered the actual number, rather than 1 (worst case). They confirmed the number was correct by comparing the IR camera software output to the actual temperature of the reactor surface measured with a thermocouple. What's not to like? What else would anyone have them do? IR cameras are widely used and reliable. It isn't like these people invented them for this purpose. Some people do invent special purpose instruments for cold fusion. That does not usually end well. - Jed
