Thermocouple thermometers are widely used temperature measuring devices in industrial production. Thermocouple sensing elements are composed of two metal wires of different materials. They have a simple structure, are easy to use, have high precision, a wide range, are vibration-resistant, and are suitable for medium and high temperature zones.

Thermocouple thermometers use bimetallic thermometers, thermocouples or thermal resistors to integrate temperature transmission, which not only meets the needs of on-site temperature measurement, but also meets the needs of long-distance transmission. They can directly measure liquid, vapor and gas media in the range of -80-+500℃in various production processes, as well as solid surface temperature Măsurare .

The temperature difference sequence was formerly known as the "thermoelectric sequence", which is a sequence arranged according to the properties of metals (or semiconductors, the same below) in the temperature difference phenomenon. When two metals are randomly selected from the sequence to form a thermocouple, at the junction with higher temperature, the current flows from the metal in the front of the sequence to the metal in the back of the sequence. The common thermoelectric series is as follows: Bi-Ni-Co-K-Rb-Ca-Pd-Na-Hg-Pr-Ta-Al-Mn-Pb-Sn-Cs-W-Tl-In-Ir-Ag-Re--Cu-Au-Cd-Zn-Mo-Ce-Li-Fe-Sb-Ge-Te-Se.
