Abstract

This paper analyses the influence of air pressure regarding the precise mass measuring process. The stability of air pressure to the mass determination process is discussed experimentally using the new M-one mass comparator. Due to the change of air pressure, air flow and vibration with regard to the weighing hanger can be arisen. The vibration of weighing hanger is from both the base and the air flow. Under air pressure control, the standard deviation of weighing process can be reduced to 0.39 æg.
