Best answer
A thermocouple is used to measure temperature. It works by producing a small electrical voltage when two different metals are joined at one end and exposed to a temperature difference. This voltage is then used to determine the temperature at that junction.

Thermocouples are commonly used in a wide range of applications, from industrial processes to household appliances, because they are durable, versatile, and can measure a wide range of temperatures, from very low to very high.
