Thermocouples are best used for measuring temperatures that can go above 100 °C. This is a bare wires bead-probe which can measure air or surface temperatures. Most inexpensive thermocouples have a vinyl covering which can melt at around 200 °C, this one uses a fiberglass braid so it can be used in high temperature measurements such as heaters and ovens.

Adafruit have a handy tutorial which covers thermocouple use including an Arduino library and example code!

Please note: we seem to have gotten a few thermocouples that have the red&yellow wires color-coded wrong. It will not damage the thermocouple or sensor if the wires are connected backwards, but temperature readings will go the 'wrong way' so if you find that the temperature is dropping when you heat up the sensor, try flipping the wires!

  1. Hey, what guage is this?
  2. I'm not sure of that detail sorry.
  3. Pending moderation
  4. Ok, could you measure the very tip of the probe? If you search AWG (american wire guage) on wikipedia, it has a table that shows how many milimeters equals what guage size. Would be really useful to know!
  5. Ah right, I didn't realise you were referring to AWG. Regardless, the actual tip of the thermocouple is around 0.9mm.


  6. Hi I have a fluke thermometer that uses K type probes will this work with it.
  7. Hi Corne,

    Yes, if you can connect it.


  8. Hi Hadley,

    How many of these would you have in stock please? Don't suppose you can get any longer items like 2 ro 3 meters.

  9. Hi Craig,

    Only five left in stock today. I haven't come across any longer ones in my travels yet but if you need some drop me an email with specs and I'll see what I can do.
