Realization of argon triple point at UME

Recently, UME has acquired an argon triple point system in order to extend its temperature scale down to 83.8058 K. The detailed description of the UME argon triple point apparatus which was developed to obtain the argon triple point plateau by means of adiabatic working principles will be presented below. A standard platinum resistance thermometer which was calibrated at argon triple point at PTB low temperature laboratory has also been calibrated in our equipment. Results related to these measurements are presented in the paper.
