Valve is connected, and the 3rd tunnel is connected with Temperature and Humidity unit.
The main control unit adopts digital integrated electronic circuit；
The Temperature and Humidity unit (8) is using high-precision AM2302 Temperature Humidity Sensors.
Operation principle of the present utility model is briefly described as below：Automatically experiment, emanometer are corrected in the humiture for carrying out emanometer
When surveying radon sampling, sampling air inlet pipe is connected to into Standard Radon Chamber, air containing the radon point two-way into sampling air inlet pipe is 1 He of gas circuit
Gas circuit 2；Air in gas circuit 1 can be adjusted by gas circuit 1 by adjusting 1 regulating valve of gas circuit due to the effect of 1 vacuum pump of gas circuit
In air flow component, then by humidifying container so that the air humidity of outflow is improved；Air in gas circuit 2 is due to 2 vacuum of gas circuit
The effect of pump, can be adjusted by the air flow component in gas circuit 2 by adjusting 2 regulating valve of gas circuit, then by drying tube by air
It is dried, through dried gas, its humidity is substantially reduced；The air that gas circuit 1 flows out same gas after 1 check valve of gas circuit
The air that road 2 is flowed out accesses emanometer after 2 check valve of gas circuit is mixed again Jing after Temperature and Humidity unit enters sampling exhaustor
Air inlet, the warm and humid angle value that main control unit is detected according to Temperature and Humidity unit and then adjust 1 regulating valve of gas circuit and gas circuit 2 is adjusted
The air flows ratio of section valve so that the various warm and humid value that emanometer gas sampled is obtained.This utility model, with digital circuit
Automatically controlled, control to do using regulating valve, the different air flows of humid gas, realized the automatic of gas sampled humiture
Control and regulation, it is ensured that the realization of various temperature and humidity conditions, are very easy to the development that humiture corrects experiment automatically.To sum up
It is described：This utility model has the advantages that simple structure, with low cost, reliable and stable, easy to use.
