In caseyou are wondering why connecting a voltmeter to a thermocouple does not make several additional thermocouple junctions (leads connecting to the thermocouple, leads to the meter, inside the meter etc), the law of intermediate metals states that a third metal, inserted between the two dissimilar metals of a thermocouple junction will have no effect provided that the two junctions are at the same temperature.

你可能会问为什么在热电偶上连接一个电压表不会产生一些附加的热电偶结点（与热电偶连接的引线，与电压表连接的引线，电压表内部引线等等）热电偶中间导体定律描述到：热电偶回路中，接入第三导体，只要第三种导体的两个接头温度相同，则回路中的总热电势不变。

If thermocouples with thin leads or long cables are needed, it is worth keeping the thermocouple leads shortand then using thermocouple extension wire (which is much thicker, so has a lower resistance) to run between the thermocouple and measuring instrument.

如果需要细的导体和长的引线，可以在保持热电偶导体较短的情况下采用热电偶延长导线来实现热电偶与测量设备的连接。
