Thermometer fixed points
Webb[1][2][3]In practical terms, a temperature scale is always based on usually a single physical property of a simple thermodynamic system, called a thermometer, that defines a scaling function for mapping the temperature to the measurable thermometric parameter. WebbITS-90. Small SRM fixed-point cells are used to calibrate small thermometers over the range from 29 °C to 157 °C. High-purity SRM metals (≥99.9999% pure) are available for the construction of fixed-point cells of In, Sn, Zn, Al and Ag …

WebbThe Fixed Point Method of thermometer calibration assures the quality and accuracy of a thermometer’s measurements. Typically, only national metrology laboratories use it. … 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.
