An error correction model for volume determination by the double-weighing in air method was also built; this model was based on the physical properties of thermal expansion. Based on the mathematical model and the working principle of the measuring device, three primary factors that affected the results were identified and analysed: the atmospheric pressure range, the weight surface desorption effect, and the mass comparator properties.
