I haven't been on in a few months, but I was researching how to calculate cumulative temps for pasteurization in my sous vide system, and I found the mother load of info regarding thermocouple design.
I'd start with this excellent video: http://www.eevblog.com/2013/02/03/eevblog-419-thermocouple-tutorial/
And then read this design analysis by TI: http://www.ti.com/lit/ug/slau509/slau509.pdf (don't worry about the chip specifics, rather the principles about thermocouple circuit design).
Hopefully this helps people understand thermocouples, and helps the HM design.
Cheers,
Dave
