Fixed points 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… WebApr 29, 2024 · A thermometer is calibrated by measurements at a series of temperature fixed points (freezing/melting points, triple points or vapour pressure points of pure materials). By using this method we insert the …
