CXF-4B Aerosol Particle Size Grading Sampler
The particle size grading sampler divides aerosol particles in the air into different size ranges and collects them on different filter membrane. CXF-4B centripetal particle size grading sampler is able to divide the aerosol particles into 4 size ranges and collect them respectively. After sampling, corresponding measurement instrument shall be used to measure the amount of aerosol (mass number or activity value, etc.) on the filter membrane at all grades, and then the particle size distribution of the sampled aerosol can be estimated. The particle diameter indicated by this instrument refers to the aerodynamic equivalent diameter.
