PROBLEM TO BE SOLVED: To reduce mean power consumption, and to lengthen the life of an incorporated battery in a radio measurement device to be used for the radio communication of measurement data. SOLUTION: Measurement data relating to the measurement object of an environment atmosphere outside a device main body 9 are measured in a first cycle by a measurement part 13. A transmission/reception part 15 transmits a radio wave on which the measurement data are superimposed to external equipment. A transmission mode changing part 21 performs the low speed transmission control of the measurement data from a transmission/reception part 15 in every second cycle which is longer than the first cycle, and when the measurement data fluctuate, the transmission mode changing part 21 performs the high speed transmission control of the measurement data from the transmission/reception part 15 in every third cycle which is longer than the first cycle, and shorter than the second cycle.
