So far I have seen, they used a battery driven handheld 4 channel
thermosensor device to measure the cold water inlet and the warm water
outlet at the heat exchanger. So far I could see from the yellow plugs,
they used Ni-CrNi thermoelements.
These can be used upto about 1200°C (I dont know the precise limit and
this depends from the insulation of the wires also)
Usually the tips are not insulated, to get the fastest response time
that is possible.
It is easy to insulate them by a short piece of thin wall silicone hose
if necessary.

Why should it be assumed that improper equipment been used in these
tests? The meter used with the thermocouples is listed in Mats
Lewan's report:
* Temperature logger Testo 177-T3 0554 1765 Usb Interface
The specification I read listed the temperature range as -40 to +120
C. Does that suggest that its accuracy goes out of specification if
the temperature is greater than 120? I assume that it keeps working
past that limit. I made an attempt to
These should be resistive or semiconductor sensors. A PT 100 resistive
sensor usually goes until 500 degrees.
Judging from the temperature limits this are semiconductor sensors.
These -and resistive sensors- are always isolated. These where not used
to measure the heat exchanger.
determine whether or not the inputs were isolated but did not see
reference to that in the specifications. How can that be determined
as this seems to be a professional meter.
This issue would be resolved if it is determined that the
thermocouples are isolated.

It is common in science and technics, some people repeat the same
error over and over because they refuse to think and instead judge
from experience and belief. They think if it worked 3 times for then
it will work 1000000 times for others.
But this is junk science,
Just want to add this: If Piantelli and Focardi made their thermic
measurements (that where much more difficult) with the same care as
Rossi, then their research is junk and this all is a waste of time.
If they connected their elements directly to the metal, using a non
insulated multichannel thermoamplifier, then they measured
thermovoltage in the metal and not in the thermoelements and these in
the metal can be influenced by the degree of hydrogen adsorption.
