Title:
濃度測定器
Document Type and Number:
Japanese Patent JP7168069
Kind Code:
B2
Abstract:
It is possible to reduce a decrease in accuracy of measuring the concentration of a measurement target gas even in a case where, in a mixture of gases, there is a gas greatly different from another gas in a rate of change in thermal conductivity with respect to temperature. The concentration measurement device includes a sensor configured to measure the concentration of a measurement target gas in a mixture of gases on the basis of thermal conductivity of the measurement target gas, the mixture of gases including two or more components, and a heating unit configured to heat the mixture of gases so that the concentration of the measurement target gas can be uniquely determined with respect to the thermal conductivity.
