Title:
MEASUREMENT DEVICE AND MEASUREMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2018/216350
Kind Code:
A1
Abstract:
The present invention enhances mass concentration accuracy. This measurement device is provided with a selection unit (15) for referring to a storage unit (13) having stored therein a plurality of correlations between the mass concentration of particles in a gas with respect to the humidity of the gas and the number density of the particles in the gas and selecting two correlations from among the plurality of correlations, and a mass concentration calculation unit (16) for calculating the mass concentration of the particles in the gas on the basis of the two selected correlations together with the number density of the particles in the gas as measured by a first number density measurement instrument and the humidity of the gas as measured by a first hygrometer.
