Alternatively, the aerosol flow rate, the flow rate of the aerosol being measured, and the flow rate and velocity of the clean gas mixed in are controlled to achieve a specific dilution ratio before sampling. However, if a counter is used to directly sample slightly high-pressure or high-pressure gas, the high-pressure gas will impact the counter, damaging it and preventing accurate measurement.

[0105] Example 2

[0111] The method of using this embodiment is as follows:

[0112] In actual work, high-pressure or high-concentration gas passes through the first air inlet and the second air inlet and pushes open the regulating member, so that the airflow can enter the first cavity through the regulating member, the second air inlet and the third air inlet, thereby achieving pressure reduction and flow control of the high-pressure or high-concentration gas.

[0113] The advantage of this embodiment is that by installing the adjustment member in the second air inlet through the elastic member, passive adjustment of the air pressure and airflow in the second air inlet can be achieved, thereby increasing the degree of automation of the entire device.
