👉 An eudiometer is a device used to measure the temperature of an object. It works by measuring the difference in temperature between two points on the surface of the object, and then converting this measurement into a readable reading. The accuracy of the eudiometer can be improved by using a thermometer or other type of thermometer with a higher sensitivity. In physics, the term "eudiometer" is often used to refer to an instrument that measures temperature differences between two points on an object's surface.
