A PT100 is the most common type of Resistance Temperature Detector (RTD). The PT100 has a resistance of 100 Ohms at 0°C and 138.5 Ohms at 100°C. PT100s are a common choice for measuring temperature in industrial processes and laboratories. They are a popular choice due to their stability, accuracy, and repeatability.
