A thermal circulator is a device used to maintain a consistent temperature in liquids. It typically consists of a heating element, a pump, and a temperature control system. These circulators are commonly used in laboratories and culinary applications, such as sous vide cooking, where precise temperature control is essential. The pump circulates the heated liquid, ensuring even temperature distribution throughout the container. This technology allows for accurate and repeatable results, making thermal circulators valuable tools in both scientific research and professional kitchens. They can be used with various liquids, including water and oil, depending on the application.
