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:

• Thermocouple 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%

Product Details:

A Type K thermocouple refers to any temperature sensor containing Chromel and Alumel conductors, that meets the output requirements as stated in ANSI/ASTM E230 or IEC 60584 for Type K thermocouples. This may be an immersion sensor, a surface sensor, wire or another style of sensor or cable.
