K Type Thermocouples are temperature sensors that are commonly used in industrial and scientific applications. These thermocouples consist of two wires made of different metals that are joined together at one end to form a junction. When the temperature at the junction changes, it creates a voltage that can be measured and used to determine the temperature. K Type Thermocouples are known for their accuracy and versatility, and are often used in high-temperature environments such as furnaces and kilns. They are also commonly used in food processing and scientific research applications.
