be careful with the effect of hydrogen on any metal (make hydrides, make brittle, leaks and then self-ignite- H can burns a µg/min according to wikipedia, check airliquide.com for safety of H2...)
maybe (I have no clue) H2 can transform the characteristics of a thermocouple, especially at high heat and pressure... Defkalion seems to use void and argon for their electronics , to protect from H. by the way, If you are not professional, be very very careful... this gas is "traitor". 2012/2/1 Robert Lynn <[email protected]> > This is a standard industrial technique, though it is slower to respond > than having the thermocouple exposed directly to the hydrogen in the > reactor. > > >
