A thermocouple is a temperature-sensing device that can be used in a wood pizza oven to accurately measure temperature. It consists of two dissimilar metal wires joined at one end, known as the hot junction, and connected to a temperature display unit at the other end. The hot junction is typically placed at the desired location within the oven, such as the cooking surface or the dome, to monitor the temperature. The temperature measurement is based on the principle that the junction generates a small electric voltage that is proportional to the temperature difference between the hot junction and the display unit. Thermocouples are known for their fast response time, durability, and ability to withstand high temperatures. They provide real-time temperature readings and are commonly used in professional wood pizza ovens to ensure precise control over cooking temperatures and consistent results.
