Platinum Resistance Thermometer

A Platinum Resistance Thermometer (PRT) is a precise device used to measure temperature. It works on the principle that the electrical resistance of platinum changes consistently with temperature. As the temperature increases, the resistance also increases in a predictable manner. PRTs are known for their accuracy and stability, making them ideal for scientific and industrial applications, such as laboratories and manufacturing. They can measure a wide range of temperatures, often from -200°C to over 800°C, and are crucial in ensuring processes that require precise temperature control, such as in pharmaceuticals or food production.
