Type K Thermocouple

type-k-thermocouple-grade-wire-extensionThe Type K Thermocouple (Nickel-Chromium / Nickel-Alumel) is the most common type of thermocouple. It’s inexpensive, accurate, reliable, and has a wide temperature range. The type K is commonly found in nuclear applications because of its relative radiation hardness. Maximum continuous temperature is around 1,100°C.

Type K Temperature Range
Thermocouple Grade Wire –454°F to 2,300°F (–270°C to 1260°C)
Extension Wire 32°F to 392°F (0 to 200°C)


Type K Accuracy
Standard +/- 2.2°C or +/- .75%
Extension Wire +/- 1.1°C or 0.4%
