• The materials for thermoelectrode has the following requirements:
high thermo-EMF is proportional and close to the character of its changes on temperature;
heat resistance (neoteleostei at high temperatures);
immutability of the physical properties over time in the pre Affairs of measured temperatures;
high electrical conductivity;
small temperature coefficient of resistance;
the possibility of production in large quantities with the same physical properties.
Chromel-thermocouple kopeleva. These thermocouples allow to measure long-term temperature up to 600°C and briefly up to 800 °C. They successfully work both oxidising and reducing atmosphere and in vacuum.
