Specifications

What Is a PT100 Sensor?

A PT100 is a type of Resistance Temperature Detector (RTD) made with platinum. The resistance of the sensor is 100 ohms at 0°C, and it changes predictably with temperature — making it one of the most accurate and stable temperature sensing technologies available. PT100 sensors are widely trusted in industrial automation, food processing, scientific research, and DIY electronics projects.

Who Is This For?

This PT100 probe is perfect for hobbyists, engineers, and professionals who need a reliable, waterproof temperature sensor for controllers, data loggers, PLCs, Arduino/Raspberry Pi projects, brewing setups, heating systems, and more.
