The sampling fan mainly has the following uses:

1. Sampling for analysis. The sampling fan can be used for the sampling of physical or chemical properties such as gas and particulate matter, providing samples for analysis or detection to determine the composition, concentration, properties and other parameters of the substance. This has important applications in environmental monitoring, industrial technology and other fields.

2. Ventilation and ventilation. The sampling fan can be used for ventilation and air exchange in a certain space to dilute and discharge harmful substances in the air to improve air quality, which is used in mines and other places.

3. Smoke emission monitoring. The sampling fan is used to sample the target gas and particulate matter in the flue gas of the emission source to monitor whether the emission concentration meets the standard, which is widely used in the environmental protection regulatory authorities.

4. Process control. Through the process gas or gas composition data collected by the sampling fan, the production process can be optimized and controlled to improve product quality, such as temperature and pressure control in the organic synthesis reactor.

5. Device protection. The sampling fan can be used in certain occasions for gas sampling and monitoring inside key equipment or process pipelines. Once harmful gases are detected, alarm and protective measures can be started in time to protect equipment safety.

6. Product testing. The sampling fan collects volatile compounds in the product for quality inspection to determine whether the product is qualified or not, which is used in product quality testing in food, medicine and other industries.

In summary, the sampling fan is mainly used for the collection and monitoring of gases and aerosols, and the samples collected by the sampling fan can be used for material analysis and testing, process control and equipment protection, environmental and emission monitoring, and product quality testing, etc., which is widely used in the fields of environmental protection, industrial production and pharmaceutical industry and plays an important role.
