<p>PROBLEM TO BE SOLVED: To provide a calorie component concentration measuring system for easily measuring gas property.SOLUTION: A calorie component concentration measuring system includes: a measuring structure 10 which measures a value of heat loss coefficient or thermal conductivity of mixed gas to be measured when a heater element generates heat at a plurality of heat generating temperatures; a concentration formula storage device 452 which stores a calorie component concentration formula having heat loss coefficient or thermal conductivity for a plurality of heat generating temperatures as an independent variable, and calorie component concentration as a dependent variable; and a concentration calculation section 355 which assigns the value of the heat loss coefficient or thermal conductivity of the mixed gas to be measured for a plurality of heat generating temperatures to the independent variable being the heat loss coefficient or thermal conductivity for a plurality of the heat generating temperatures of the calorie component concentration formula, and calculates the calorie constituent concentration of the mixed gas to be measured.</p> |
