ETW-3A Intelligent Aerosol Particle Size Sampler

ETW-3AIntelligent aerosol particle size sampler

ETW-3AThe intelligent aerosol particle size sampler is a newly designed product by our company. It has a large sampling flow rate, good stability, an AC power supply, convenient use, small size, and light weight. It is a powerful tool for on-site aerosol particle size sampling.

The intelligent aerosol particle size sampler has the following characteristics:

1. Standard flow rate, sampling microcomputer control of DC motor, automatic setting of time and flow rate,

2. At present, glass flow meters are commonly used in China to regulate flow, but their accuracy and error are relatively poor,

3. This is a new design by our company, which uses a microcontroller to control the flow rate (without a glass flowmeter), and the sampling system is applied for invention. High precision, stable flow, and advanced technology.

4. Automatic constant flow rate. Prevent voltage fluctuations from affecting flow rate and achieve high sampling accuracy.

Purpose:ETW－3AThe aerosol particle size distribution sampler is a multi-stage porous cascade impactor used to measure the size distribution and total content of various solid and liquid particles in the air. It can be widely used for sampling and monitoring of aerosol content and size distribution in environmental protection, labor health, atmospheric science and other departments, as well as for aerosol sampling research in relevant scientific research departments, providing scientific basis for evaluating the degree of environmental air pollution and its control measures.
