[TriEmbed] replacement thermocouples for reflow oven

[Jon Wolfe]

I use that exact thermocouple in my homemade oven. I also use the max 31855 breakout from adafruit.  I think if the old one was a k type and the oven has a way to calibrate,  you maky be ok. The main difference in the types are the temp-voltage curve characteristic, which is a function of materials used and construction. 

Many multimeters have a thermocouple function, so you could use that for testing.

</div>OK, finding affordable thermocouples didn't take long.

If I buy some of these Adafruit type K thermocouples (replacing the heat 
shrink on the end with something that can handle higher heat and paying 
attention to "polarity") and arrange to switch them into my oven 
controller (i.e. either/or with the existing ones), what's likely to 
happen? If the oven also uses type K should this "just work"? Is there 
some way to determine what type of thermocouples I have now? (this isn't 
mentioned in the manual)
