Abstract

Abstract This study focuses on the experimental demonstration of the definition of kelvin using a triple point of water (TPW) cell and estimates the measurement uncertainty. The first part of this article is to construct the measurement setup and perform the measurements. The second stage is related with the calculation of uncertainty according to guides to the expression of uncertainty in measurement. The experiment in this study can be a practical and convenient method to show the unit as the fraction 1/273.16 of the thermodynamic temperature of the TPW, 273.16 K.
