I just want to share you a very simple trick to check the temperature of your soldering iron tip. By using this method I got a very good repeatability of the measurements up to the degree (C°) despite using a simple sub 5$ k-type probe. Don't think you can go any better than this even by using a dedicated tip thermometer.

  1. split the k-type thermocouple wires so you can stick your
      soldering iron tip inside the two wires.

  2. tin the tip of the soldering iron

  3. stick the soldering iron tip between the two wires of the thermocouple

  4. just slightly pull the thermocouple wires so they get good thermal contact with the soldering iron tip

  5. you should now have a very stable and accurate temperature reading on your multimeter

I attached a photo just in case my English is too poor.

PS: just ensure the two wires doesn't short before touching the soldering iron

Nice trick! I wish I had known about it before I bought a dedicated tip thermometer  |O
