Nickel chromel alumel KP KN K type thermocouple wire

  • K type thermocouple wire

There are multiple types and grades of thermocouple wire.Each type of thermocouple wire has a specific combination of metal alloys.This combination is what defines the type of thermocouple.Thermocouple grade wire is used to manufacture thermocouple probes.Thermocouple grade wire is normally used for the junction and inside the stem sheath.


Type K Temperature Range:

  • Thermocouple grade wire, –454 to 2,300F (–270 to 1260C)
  • Extension wire, 32 to 392F (0 to 200C)

Type K Accuracy (whichever is greater):

  • Standard: +/- 2.2C or +/- .75%
  • Special Limits of Error: +/- 1.1C or 0.4%

Consideration for bare wire type T thermocouple applications:


  • Aerospace and Composites
  • Aluminum
  • Food and Pharmaceutical
  • Forgings
  • Glass, Ceramics, Clay Tiles, Bricks
