Wire probes, also known as wire thermocouples or wire temperature probes, are a type of temperature sensor consisting of two wires made from different thermocouple materials. These wires are joined together at one end to form a measuring junction, while the other end is connected to a measuring instrument or temperature controller for temperature monitoring and control.

Wire probes are widely used in various industries and applications where temperature measurement is critical, such as HVAC systems, industrial process control, research laboratories, food processing, and manufacturing. They are particularly useful in applications that require flexibility, easy installation, and versatility in temperature measurement.
