Paul;

Thanks.  my head is not hurting because I will have to read it 
several more times and look up a few words.  But, I do have a much 
better idea about the construction and operation of the cell than I 
did before and for me, thats what its all about.

The effect of temp. seems a lettle extreme considering the temp. we 
are dealing with.

I'm  trying to make a list of variables and then prioritize their 
effect on accuracy.  right now my list is short.
impedance of measuring  instrument should be very high, >1meg.
Temp. should be about 700 F. and very stable
Sensor location should be where it gets fresh air.  
I'm still working with the old two wire sensors and trying to squeeze 
as much as possible with my lo-tech mentality.
