WZP PT100 temperature probe with platinum resistance -200°C to +500°C

For precision temp sensing, nothing beats a Platinum RTD. Resistance temperature detectors (RTDs) are temperature sensors that contain a resistor that changes resistance value as its temperature changes, basically a kind of thermistor. In this sensor, the resistor is actually a small strip of Platinum with a resistance of 100 ohms at 0°C, thus the name PT100. Compared to most NTC/PTC thermistors, the PT type of RTD is much most stable and precise (but also more expensive) PT100’s have been used for many years to measure temperature in a laboratory and industrial processes, and have developed a reputation for accuracy (better than thermocouples), repeatability, and stability.
