Fixed points of thermometer

The precision or resolution of a thermometer is simply to what fraction of a degree it is possible to make a reading. For high temperature work it may only be possible to measure to the nearest 10 °C or more. Clinical thermometers and many electronic thermometers are usually readable to 0.1 °C. Special instruments can give readings to one thousandth of a degree. However, this p… WebOct 12, 2024 · This property creates what are called fixed points that we can use to reference our thermometers. Stick a thermometer with no markings into boiling water and whatever reading it settles at is (well, should be) 100 degrees Celsius. Take the same thermometer and stick it into a bucket of ice water, and that reading is 0 degrees Celsius.

The ITS-90 is designed to represent the thermodynamic (absolute) temperature scale (referencing absolute zero) as closely as possible throughout its range. Many different thermometer designs are required to cover the entire range. These include helium vapor pressure thermometers, helium gas thermometers, standard platinum resistance thermometers (known as SPRTs) and monochromatic radiation thermometers.
