Fixed points of thermometer
WebGovInfo U.S. Government Publishing Office WebJun 13, 2024 · 1 Every individual thermometer of any type is calibrated to give the correct temperature reading at the fixed points. This is why they are called fixed points. There is no guarantee that the thermometer will read the correct temperature at other points.
