In the marine Diesel engine, there still remains problems about the relation between thermal loads of engines and the indicated values of thermometer. Therefore, the exact measurement of exhaust gas temperature has expected up to the present. The indicated value is mainly affected by two factors which are the measurement factors of exhaust gas temperature and the gas flow in the exhaust pipe, and it is still not clear how these two factors affect the indicated value.In this study the measurement factors affecting on the indicated value were examined, using two kinds of steady state exhaust gases in the duct and the thermometer well which was filled several thermocouples up the axial surface. Owing to the results, the temperature of the tip of well usually is different from gas temperature, even if the longitudinal length of well takes enough. Therefore, it seems that it is not suitable to make the reading gas temperature, the correcting of the reading is necessary to take account thermal characteristics of well in the duct.
