IEC854-1 Type K thermocouple bare wire for Thermocouples Sensor

  • Type K Thermocouple Wire

Type K thermocouples usually work in most applications as they are nickel based and exhibit good corrosion resistance. It is the most common sensor calibration type providing the widest operating temperature range. Due to its reliability and accuracy the Type K thermocouple is used extensively at temperatures up to 2300°F (1260°C). This type of thermocouple should be protected with a suitable metal or ceramic protection tube, especially in reducing atmospheres. In oxidizing atmospheres, such as electric furnaces, tube protection is not always necessary when other conditions are suitable; however, it is recommended for cleanliness and general mechanical protection. Type K will generally outlast Type J because the JP wire rapidly oxidizes, especially at higher temperatures.


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%
