Is this a K Type sensor?

[DocDingwall]

I'm trying to do a similar thing just now with the MAX6675 and the breakout board from Sparkfun (at least I think it's the MAX6675, I'm at work now). It's not clear to me if the wires from the female thermocouple socket to the MAX6675 breakout also need to be K type or is copper OK? At what point is it OK to switch to copper? Could the thermocouple lead be soldered right to the breakout board for prototyping?

Thanks for your help. Sorry if I should be starting a new thread.

Anyplace the wire material changes you need a reference temperature and calcs. A couple exceptions here and there though.

I'm writing some code for this device also. I'm wondering why the shift of 5 places to the right when in the data sheet it looks like only 3 shifts right should put the Temperatures lsb in the correct location.

At least that's how my initial coding is. I'll try it tonight.
I also use MSBPOST=2 :

Get6675_Raw:
LOW NCS:PAUSEUS 1
Shiftin SO, SCK, MSBPOST, [raw1\16] ' Read 16 bit temperature register
raw1 = raw1>>3
HIGH NCS
RETURN

OK so I tried the code. Now I see you guys are right with the 5 bit shift.
The device is capable of 12bits or 0.25 deg resolution if shifted only 3 times.
