After the heating circulating water passes through the water bath reagent tank 4 and the constant temperature heating jacket 5, it enters the water pipe of the sample placement tank 10. After the temperature in the sample placement tank 10 transmits and collects data to the regulation and processing unit 12 through the second temperature sensor 11, the regulation and processing unit 12 outputs to adjust the temperature of the heating tank 2 to control the injection temperature; similarly, after the humidity in the sample placement tank 10 transmits and collects data to the regulation and processing unit 12 through the humidity sensor 13, the placement tank cover 17 is covered on the sample placement tank 10, and the regulation and processing unit 12 outputs to drive the compressor 14, the fan 15 and the heat exchanger 16 to adjust the internal humidity of the sample placement tank 10 to the set humidity to control the injection humidity; when the internal temperature and humidity of the constant temperature heating tank 10 reach the set values, the placement tank cover 17 is placed on the sampling end top of the continuous flow analyzer to make the sampling environment of the continuous flow analyzer reach the best conditions.
