Thank you for your post.
I would not recommend connecting thermocouples to an ADC10 or 11 as the resolution of these units is not sufficient to see the small changes in voltage exhibited by thermocouples.
Instead I would recommend our TC-08 unit as this is built for use with thermocouples and has the right input voltage range needed to see the small changes of thermocouple outputs. It can accept any type of thermocouple and will do all the necessary scaling in the software.
Hope this helps
