Abstract

The International Avogadro Coordination aims at determining the Avogadro constant by measuring the molar mass, lattice parameter and density of a ²⁸Si single crystal. As the temperature dependent quantities are measured in different apparatuses, the consistency of the temperature measurements has to be proven. An electronic temperature reference and a standard platinum resistance thermometer (SPRT) are used - in a first round - to compare the temperature measurements at the INRIM and PTB.
