NEW PRODUCT – Thermocouple Type-K Glass Braid Insulated – K

Thermocouple Lrg

NEW PRODUCT – Thermocouple Type-K Glass Braid Insulated – K. Thermocouples are best used for measuring temperatures that can go above 100 degC. 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 degC, this one uses a fiberglass braid so it can be used in high temperature measurements such as heaters and ovens.

  • K type thermocouple with glass over-braiding
  • Good up to 500 degrees C (900 DegF)!
  • Color-coded wires
  • 1 meter long (a little more than 3 feet)

Best used with a thermocouple amplifier such as the MAX6675 (pictured above, not included). We have a handy tutorial which covers thermocouple use including an Arduino library and example code!

  1. I wonder if this will work for the eternal question, “How hot is my soldering iron?”

  2. will definitely work for that 🙂

  3. Tip: sell it with a standard thermocouple connector.

    I have a ‘k’ thermocouple thermometer, but the one problem it has is the wire is very brittle and can’t take much flexing. Replacement probes aren’t something you’ll find in your local walmart, so adding the standard connector should broaden the appeal of the product, imho.

  4. s7, it would cost 2x as much – if you want a thermocouple with standard connectors, check omega.com

  5. Hey ladyada, thanks for the plug in the tutorial! Nice looking breakouts.

    signal7, like ladyada said the standard connectors do drive up the cost. I have some breakouts using “standard” connectors (ryanjmclaughlin.com/shop) and thermocouples, but I commonly get people asking why they are so expensive. Its just due to the thermocouple hardware. Sometimes it is just a bit overkill for a prototype, but these boards fill the gap.

  6. I’ve actually used headless nails (small brads) to make ad-hoc connectors, with a rubber pencil eraser as a spacer in between and heat-shrink around the outside. Don’t use galvanized nails, btw. Of course, if you can afford a true Omega unit, you can probably afford the connectors too. Just sayin’
