Thermocouples are used in a wide range of industries, and Pyrosales have an information guide online to help you determine the most suitable product for your processes.

The following details are a brief introduction to the types and uses of thermocouples.

Type B:


Used extensively in the steel and iron industry to monitor temperatures and chemistry throughout the steel making process.

Type C:

Widely used in space vehicles, nuclear reactors, industrial heating, or wherever extremely high temperatures may be present. Also used in high-pressure research. Well suited for vacuum furnaces at extremely high temperatures.

Type E:

Used in sub-zero, oxidising or inert applications. Ideal for cryogenic, pharmaceutical, and chemical applications where critical measurements are required in small increments.

Type J:

Recommended for vacuum, inert, and reducing atmospheres. The thermocouple can be used exposed or unexposed.

Type K:


Used for measurements in many different types of environments such as water, mild chemical solutions, gases, and dry area. Found in engines, oil heaters, and boilers. Used as thermometers in hospitals and the food industry.

Type N:

Has outstanding thermoelectric stability. Can be used in vacuum or controlled atmospheres. Developed to replace type K in nuclear applications.

Type R and type S:

Heat treating and control sensors, semiconductor industry, glass manufacturing, ferrous and non-ferrous metals.

Type T:

Used in food monitoring and environmental applications.
