One of the characteristics of at least Ni-H LENR is the likelihood that the energy from the NAE is transported away from the reaction site via low energy radiation. This creates the possibility that, like seen in a microwave oven, the surrounding apparatus may become hotter than the source. Rossi appears to utilize this in his eCat-X to heat tungsten plates to be incandescent hot. In such situations, thermometry is problematic for several reasons. It is possible that some portions of the reactor are hotter than others - which portion do you measure? It is possible that a thermocouple could get heated hotter than the spot it is trying to measure by radiation thermalization. In such cases, calorimetry is probably the best bet to guarantee that you are truly not violating your assumptions in inferring heat from temperature measurements. Also temperature measurements must use multiple redundant technologies to insure that remote heating effects are identified if they exist.
Could the Lugano team have chosen infrared themometry for this very reason?
