This K-type thermocouple extension wire can be purchased by the meter, allowing for additional customization of your temperature sensing system. When you connect it to your thermocouple, be sure to hook it up with the red wire to the negative thermocouple wire and the yellow wire to the positive. If you hook the wire up backwards, the temperature reading will be incorrect.

You should use a K-type thermocouple connector to attach this wire to your thermocouple, since the metals used in ordinary terminal blocks or solder can interfere with the thermocouple voltage by changing the junction.


  • Extends the wires of a K-type thermocouple
  • Cut to your chosen length

Thermocouple Accessories

Thermocouples cannot easily be soldered, since adding an additional metal junction will throw off the readings. The following products will help connect or extend thermocouple wires.


You can use this extension wire and a thermocouple connector to extend any of the following thermocouples:
