The redefinition of the kilogram introduced new challenges for National Metrology Institutes (NMIs), particularly in ensuring accuracy and repeatability in mass transfer measurements. This study focuses on a comparative analysis of various mass comparators, with particular emphasis on vacuum conditions and the impact of vibrations on measurement stability. The relevance of this study to transport lies in improving vehicle weighing accuracy, which is essential for road safety and fuel efficiency. The research highlights the performance of the AVK1000 comparator compared to previous models, identifies discrepancies, and discusses modifications aimed at improving its functionality. The study also underscores the necessity of monitoring environmental factors to maintain high measurement reliability.
