I've been trying to say multiple times that the meter measures

But that's for *air* anyway. We want to know the steam quality. This
probe does *not* do this.
It takes an expensive complicated system to measure steam quality and
even then, the one I found on the market needs an overpressure of some
amount so that it can expand it into a chamber and then measure the
resulting temperature,
Not according to the Delta Ohm company or the
Testo company. They say their meters tell you
the enthalpy per kilogram of steam, so all you
have to do is determine the mass.
Jed, stop it! They don't mention steam. That
meter measures "air quality." Not "steam quality."
Let me repeat, they don't say what you just
claimed they said. They said something else that
you translated into what you said, making
assumptions. That gets you into trouble!
Perhaps you know more than the engineers at
these companies, and perhaps you are right and
they are wrong. I doubt that. I'll go with those
companies and with Dr. Galantini. I will also go
with the results of the second test with water, which confirmed the steam test.
Well, Dr. Galantini hasn't said squat about this.
Where is his report? And the "engineers at these
companies" didn't say what you reported.
Jed, if those steam quality "measurements" are a
part of your basis for confidence that Rossi is
real, please let me know, so I can revise my own opinion!
Okay, Krivit got a mail from Galantini:

Good morning, on the request made to me today,
as I have repeatedly confirmed to me that many
people have requested in the past, I repeat
that all the measurements I did, during tens of
tests done to measure the amount of not
evaporated water (read liquid water, TN) present
in the steam produced by E-Cat generators,
always was made providing results in % of
mass, since the used device indicates the grams
of water by cubic meter of steam.
I confirm that the measured temperature always
was higher than 100,1°C and that the measured
pression in the chimney always was equal to the ambient pressure.
The instrument used during the tests performed
in the presence of Swedish teachers was as
follows: 176 Text Code 0572 H2 1766 .
"The used device indicates the grams of water by cubic meter of steam."
The device is the Testo (that's a translation
artifact, the "Text Code." This is
http://www.testosites.de/export/sites/default/datalogger2011/en_INT/local_downloads/brochure_EN.pdf
Testo 176 H2 in this brochure.
The device does log (it's a data logger) g/m^3.
But I'm pretty sure that this is a calculated
measurement, it's grams of water *vapor* per
cubic meter of *air.* Not "steam" as he says. I
can't find any hint that this device is intended
to measure steam quality. I was unable to find an operating manual.
There is no sensor in the device that would
detect other than water vapor. It's an RH meter!
It's looking now like Galantini did err.
Maybe some hero will appear with magic
confirmation of how to measure steam quality with an RH meter!
