But there are some difficulties in getting the accuracy of measurements. This paper deals with a measuring device of atmospheric pressure based on variation of boilib points of water. Such devices already have been studied, but never have we heard of its utilization. It is the reason why the temperature of boiling points is depended on the position where the temperature sensor is placed. So the authors made an attempt to use the float on which the temperature sensor is attached. In this way, temperature of the sensor could be kept more steable than that without the float. As the results, it was found that the variation of the atmospheric pressure, about 2 mmAq, could be measured by using this device.}, pages = {131--135}, title = {ATMOSPHERIC PRESSURE MEASUREMENT BY MEANS OF VARIATION OF BOILING POINT OF WATER}, volume = {26}, year = {1978} }
