What aspects should be paid attention to the correct use of thermocouple?

Thermocouple in many parts of industry, equipment used more widely, but there are a lot of people can't correct use, this not only affects the work efficiency, can bring more economic loss, especially the work of the error of measurement, because in the process of the use of the thermocouple, if not properly used, will produce the size measurement error, and thus affect the measured temperature of accurate, reliable, and the correct and rational use of thermocouple is very important. In practice, the correct use of thermocouple, attention should be paid attention to the following two aspects: ( 1) Using the method of correct and reasonable to treat the thermocouple reference junction. （ 2) Understand the related factors affecting the thermocouple temperature measurement error, and adopt the correct methods to overcome them.
