| Question: |
| Are the polarities of type J thermocouple wires color coded? |
| |
| Answer: |
Yes, ANSI/MC96.1 Red is negative and white is positive (Japanese JIS C 1610-1981 is the opposite).
And thanks to your question, we have now updated our website to include a PDF file of specifications and color coding of the most common thermocouple types (as well as a few less common).
The chart may be found here:

| Question: |
| How can I determine the thermocouple type on old unmarked thermocouples? |
| |
| Answer: |
| The easiest way is to strip the wire back until you can see the color of the insulation on each leg of the thermocouple and then compare that to the color chart here: Thermocouple Chart
