The means of accurately measuring temperature has long fascinated people. One of the differences between temperature and other physical concepts such as mass or length, is that it is subjective. Different people have different perceptions of what is hot and cold. To make objective measurements we must use a thermometer in which some physical property of a substance changes with temperature in a reliable and reproducible way.

One of the most common thermometers is the Pt100 sensor otherwise known as a Platinum Resistance Thermometer or a resistance temperature detector RTD. These temperature sensors make use of the variation of resistance of high purity platinum wire with temperature. This variation is predictable enabling accurate measurements to be performed.
