Abstract:
A measurement apparatus includes: a number concentration measurement device configured to measure a number concentration of particles in a air; a humidity measurement device configured to measure a humidity of the air; and a air concentration measurement device configured to measure a concentration of a specific air in the air, wherein a mass concentration of the particles in the air is calculated based on a measured number concentration, a measured humidity, a measured concentration of the specific air, and a predetermined correlation between the number concentration, the humidity, and the concentration of the specific air, and the mass concentration of the particles in the air.
