Abstract
The present invention is one that, even while cooling exhaust gas without dilution, makes it possible to accurately measure particle concentration, and provided with: a particle concentration measurement device; a sampling cooling pipe that cools the exhaust gas collected from an exhaust gas transfer pipe to a measurable temperature of the particle concentration measurement device without dilution, and introduces the cooled exhaust gas into the particle concentration measurement device; a temperature sensor that detects temperature of the exhaust gas flowing into an exhaust gas inlet; and a calculation device that, from the detected temperature by the temperature sensor and the temperature of the exhaust gas introduced into the particle concentration measurement device, corrects measured particle concentration by the particle concentration measurement device in real time to calculate the particle concentration of the exhaust gas flowing through the exhaust gas transfer pipe.
