A COST SAVING METHOD FOR DETERMINING AIR DENSITY IN WEIGHING

C. Müller-Schöll, D. Goessi

Abstract

This paper promotes the artefact method for determining the air density for weighing and mass calibrations in industrial mass calibration laboratories. Artefact prototypes were manufactured and air density was determined using these artefacts for a proof of concept. Uncertainties are in an acceptable size. Comparison to the traditional method (measurements of air pressure, temperature, and humidity) shows agreement within uncertainties. Substantial economic advantages of the artefact method are identified compared to the traditional method.
