Common commercially available thermocouples are specified by ISA (Instrument Society of America) types. Type E, J, K, and T are base-metal thermocouples and can be used up to about 1000°C (1832°F). Type S, R, and B are noble-metal thermocouples and can be used up to about 2000°C (3632°F).
The following table provides a summary of basic thermocouple properties. For more detailed specifications of individual thermocouples, please consult the sensor manufacturer.
