K Type Thermocouple

K Type Thermocouple

Type K Thermocouple (Nickel-Chromium / Nickel-Alumel): The type K 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.

Features

  • Temperature Range:
    Thermocouple grade wire, −454° to 2,300°F (−270 to 1,260°C)
  • Extension grade wire, −32° to 392°F (0 to 200°C)
  • Melting Point, 2550°F (1400°C)
  • Accuracy (whichever is greater):
    Standard: ± 2.2C% or ±.75%
  • Special Limits of Error: ± 1.1C or 0.4%
