Hey Morris, is there a reason you don't want to stick a thermocouple
in the tube for your temp measurements as others have suggested? It
would sure simplify this section, and, you could get lots of design
help on sci.electronics.design to raise the thermocouple output
voltage nearer 5v at 537*C.
Also I suspect you have thought that if the temp sustains itself or
starts to run away, your Ardiuno will sense this and start limiting
hydrogen input and/or pump more water.

My concern if he is switching a relay on/off to control temp, is that the on/off
time will be large per cycle. Using a thermocouple controller operating an SCR
or other such switch gives significantly finer and quicker, more proportional
control to avoid overruns. But, it might cost a couple hundred $, and Morris is
operating on a tight budget. If this is really dealing with nuclear reactions,
maybe the control is important. He doesn't want a runaway reaction.
