Fixed point of a thermometer
WebApr 3, 2024 · In the high-temperature range above the copper fixed point (1084.62 °C), melting transition temperatures of metal–carbon (M–C) eutectics are evolved as reference fixed points to disseminate ... 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…

WebThe ITS-90 defines the fixed points of temperature, the type of instrument along with method to interpolate in between fixed points of temperature （Table 2.1, Table 2.2 ）. For the temperature range used in meteorological observation, a platinum resistance thermometer is specified as the interpolate instrument. Webfrom –50 °C to 100 °C. In addition, fixed-point calibrations are provided at the TPW, the ice MP, and the Ga MP (thermometer o.d. <3.6 mm). The calibration report provides an ITS-90 based table of measured bath or fixed-point temperature versus thermometer resistance, calibration uncertainties, and the thermometer calibration coefficients.
