J Type Thermocouple:

Element Combination:

Positive Leg: Iron

Negative Leg: Copper – 45% Nickel (constantan)

Temperature:

0-760 ºC

32-1400 ºF

Application:

Type J thermocouple is a very common and general purpose thermocouple
It has smaller temperature range and a shorter lifespan at higher temperatures
It is suitable for vacuum, reducing, or inert atmospheres.
It has Oxidizing atmosphere with reduced life.
Iron oxidizes rapidly above 538 °C [1000 °F] so only heavy gauge wire is recommended for high temperature.
Bare elements should not be exposed to sulphurous atmospheres above 538 °C [1000 °F].
