ETW-3 Aerosol Particle Size Distribution Sampler

ETW-3 Aerosol Particle Size Distribution Sampler The aerosol particle size distribution sampler is a multi-stage, multi-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 in environmental protection, labor health, atmospheric science, and other sectors for sampling and monitoring aerosol content and size distribution, as well as in related research departments for aerosol sampling studies, providing a scientific basis for assessing the degree of air pollution and its control measures. ETW-3 Aerosol Particle Size Distribution Sampler The main feature of this sampler is its ability to simultaneously determine the number of aerosols and their particle size distribution, both of which are essential parameters for assessing air quality. This sampler has a high capture rate, a sturdy structure, stable performance, and is easy to use. This sampler simulates the anatomical structure and aerodynamic characteristics of the human respiratory tract. It employs the principle of inertial impaction to collect particles suspended in the air on various collection plates according to their aerodynamic equivalent diameter. The collected particles can then be analyzed through weighing or physical, chemical, and radiological property assessments to evaluate the potential harm of environmental aerosols to human health.
