Are you sticking the thermocouple head in SAC solder? Be careful!
Once you stick the t/c in SAC solder and melt to 250C (which bwt is
above the 185C curie point) the chromel which contains 90-percent
nickel and 10-percent chromium and alumel which contains approximately
95 percent nickel, with aluminum, silicon, and manganese making up the
other 5 percent will alloy with the tin, changing the temperature
e.m.f relationship. You may not have a working thermocouple
afterwards.
