Title:
MEASUREMENT DEVICE AND MEASUREMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2018/131470
Kind Code:
A1
Abstract:
The present invention is a measurement device characterized by: being provided with a numerical density measuring instrument 20 for measuring the numerical density of particles in a gaseous body, a humidity measuring instrument 24 for measuring the humidity of the gas, and a gas concentration measuring instrument 22 for measuring the concentration of a specific gas in the gaseous body; and the measurement device calculating the mass concentration of particles in the gaseous body on the basis of a correlation between: a measured numerical density, a measured humidity, and the measured concentration of the specific gas; a previously-obtained numerical density, humidity, and the concentration of the specific gas; and the mass concentration of the particles in the gaseous body. The present invention addresses the problem of reducing the size and cost of a measurement device.
