This research, through experiments on influences of the solar radiation and radiation from surrounding objects, which can cause errors during air temperature measurement using a thermocouple, has made clear the effects of the solar-radiation shield length in the vicinity of the temperature sensing element of the thermocouple as well as the effects of the increase in heat transfer rate for the purpose of promotion of heat exchange between the thermocouple and the air. On the basis of the results,the decreasing method of the measurement error, and the measurement accuracy and problems of a ventilated thermocouple type thermometer were examined. Furthermore,because air temperature may change cyclically at a rate of about 1℃ per several seconds, for the purpose of measurement of a value close to the average value, a ventilated thermometer (which is made of copper and cylindrical in shape) whose sensing element has been increased in heat capacity has been manufactured and the accuracy of the thermometer was examined through experiments.
