Type J: The Iron - Constantan "J" curve thermocouple is the most widely used thermocouple; it is versatile and has a relatively low cost. It has a positive Iron wire and a negative Constantan wire and is recommended for reducing atmospheres. The operating range for this alloy combination is from 0° to 750° C (32° to 1380° F) for the largest wire sizes. Smaller size wire should operate in correspondingly lower temperatures.

Type T: The Copper - Constantan "T" curve thermocouple, with a positive Copper wire and a negative Constantan wire, is recommended for use in mildly oxidizing and reducing atmospheres at temperatures from 0° to 350° C (32° to 660 °F). They are suitable for applications where moisture is present.

This alloy is recommended for low temperature work since the homogeneity of the component wires can be maintained better than with other base metal wires. Therefore, errors due to inhomogeneity of wires in zones of temperature gradients are greatly reduced.

Type K: The Chromel™ - Alumel™ "K" curve thermocouple is often used at high temperatures. It has a positive Chromel™ wire and a negative Alumel™ wire and is recommended for use in clean oxidizing atmospheres. The operating range for this alloy is from 0° to 1250° C (32° to 2280° F) for the largest wire sizes. Smaller size wire should operate in correspondingly lower temperatures.

Type E: The Chromel™ - Constantan "E" curve thermocouple has the highest emf of all standard thermocouples. It has a positive Chromel ™ wire and a negative Constantan wire and is recommended for use in oxidizing, inert or dry reducing atmospheres or for short periods of time in a vacuum. These elements must be protected from sulfurous and marginally oxidizing atmospheres. Type E thermocouples can be used for temperatures from 0° to 900° C (32° to 1650° F).

Thermocouple Insulation Types

GP - General Purpose thermocouples that are comprised of a pair of thermocouple wires inside a tube. These are used to measure temperatures of 260° C (500° F) or less.
