What is another word for platinum thermometer?
Pronunciation: [plˈatɪnəm θɜːmˈɒmɪtə] (IPA) 
A platinum thermometer is a device used to measure temperature accurately. It is made from platinum, which has a high resistance and a stable temperature coefficient. However, sometimes the term "platinum thermometer" is used interchangeably with other similar devices. For instance, a thermocouple is a device composed of two different metals that produce a voltage proportional to the temperature difference between them. Resistance thermometers, on the other hand, use resistance changes in materials such as platinum to measure temperature. Another synonym for a platinum thermometer is a primary standard thermometer, which is a device that is calibrated directly to an international temperature scale. Regardless of the term used, measuring temperature accurately is essential in many scientific and industrial settings.
