Specifically, when the humidity measuring device 100 is operating normally, if the difference between the second temperature and the first temperature is within a preset range, it is determined that the humidity monitoring device is operating normally. That is to say, the second temperature of the sampling gas in the gas transmission main circuit 130 is basically the same as the first temperature of the sampling gas in the gas flow regulating branch circuit 160 , and when the difference is not large, it means that the humidity monitoring device 100 is operating normally .
