It has the advantages of good linear relationship between temperature and potential, reliable thermal stability, and low price. Paired with display instruments, it can directly measure the temperature of liquid, steam, and gas media. It can partially replace platinum rhodium thermocouples as a high-temperature measurement tool for high-tech metallurgical industries, high-temperature electronic thermoelectric system structural engineering, space transportation vehicles, and nuclear reactors.

The relationship between the thermoelectric potential of tungsten rhenium thermocouple and temperature conforms to the ZBN05003-88 scale table, which is equivalent to the ASTME696-84 standard. It can be used in a vacuum, reducing, and inert atmosphere within the temperature range of 0-2300 ℃. Tungsten rhenium thermocouples with special protective tubes can also be used for a long time in an oxidizing atmosphere at 1600 ℃, and their price is lower than that of platinum rhodium thermocouples.
