Thanks for your reply Markus, It is a good idea. The main problem I see is that we need to measure high temperatures. I do not know exactly how much, but around 1200ºC. And this only measures halfway. Do you know if there is a sensor for arduino with this possibility?

I am just doing this for a medical project.

Would be measured by an infrared thermometer.I am contacting you to see if anyone is interested, or know how, to attach an infrared thermometer with data logger that Liam is manufacturing for thermocouples.By this, we can obtain pairs of temperatures at the same point. Both outside and inside of the wall, in order to obtain among other data, values of thermal conductivity and heat capacity of each material.Thanks in advance for your cooperation and interest.
