Product Description

Particle (PSL) Filtration Efficiency Tester



Particle Filtration Efficiency Tester is used to test the filtration level of aerosol particles by respirator filter element under certain environmental conditions.

The aerosol particles (PSL-Polystyrene Latex) with a certain concentration and particle size distribution are generated by the aerosol generator, and pass through the tested sample at the specified air flow rate. The concentration of the particles before and after the test sample is tested, and the filtration efficiency of the tested sample to the particles is evaluated by the percentage of the decrease of the particle concentration.

SM4315C-Pro tester uses high-efficiency aerosol generator, high-precision laser multi-channel aerosol particle counter, Isokinetic sampling head, laminar flow sampling pipeline, precision differential pressure sensor and precision flowmeter. It is controlled by microcomputer to precisely control the air flow and aerosol concentration

By replacing the test head, SM4315C can test the filtration efficiency of respirator, masks and protective clothing.


Testing Scope:Medical surgical mask, Disposable medical mask, Medical protective mask, etc.
