| 摘要 |
The present invention relates to a multi fixed-point cell for calibrating a thermometer and a thermometer calibration apparatus using the same, wherein measuring errors can be checked by using a property of constant temperature of a metal on the basis of a phase transition and wide range of temperature region can be measured by one time calibration, thereby capable of increasing efficiencies of time and cost which are taken for calibration. In a multi fixed-point cell for calibrating a thermometer according to the present invention, a thermometer inserting hole in which a thermometer is inserted is formed at one side and at least two reference material inserting holes in which reference materials having different phase transition temperatures are inserted respectively are formed on a same plane as that of the thermometer inserting hole so as to be spaced apart each other.
