Type J Thermocouple

Type J Thermocouple: The type J is also very common. It has a smaller temperature range and a shorter lifespan at higher temperatures than the Type K. It is equivalent to the Type K in terms of expense and reliability.

Type J Temperature Range:
  • Type J Thermocouple Grade WireThermocouple grade wire, -346 to 1,400F (-210 to 760C)
  • Extension wire, 32 to 392F (0 to 200C)

Type J Accuracy (whichever is greater):
  • Standard: +/- 2.2C or +/- .75%
  • Special Limits of Error: +/- 1.1C or 0.4%

Consideration for bare wire type J thermocouple applications:
  • The Type J Is Well Suited To Oxidizing Atmospheres
