Multi-channel particulate filtering efficiency comprehensive tester RF4315A

Multi-channel particulate filtering efficiency comprehensive tester (salty)

Multi-Channel Particle (NaCl) Filtration Efficiency Tester

Model: RF4315A

The multi-channel particulate filter efficiency comprehensive tester is used to test the level of salt (sodium chloride) particulate matter filtered by the filter element of the respirator under certain environmental conditions.

Aerosol particles (sodium chloride) of a certain concentration and particle size distribution are generated by the aerosol generator, pass the measured sample at a prescribed gas flow rate, the concentration of particulate matter before and after the sample is tested, and the measured sample is evaluated by the percentage of decrease in particulate matter concentration The filtration efficiency of particulate matter.

The RF4315A tester uses an efficient aerosol generator, a high-precision-multi-channel-laser scattering particle size sensor (photometer method), a precision differential pressure sensor, and a precision flow meter. It is controlled by a single-chip computer to accurately control the air flow and aerosol concentration.

By replacing the test head, the RF4315A-Pro can test the filtering efficiency of masks, respirators, and protective clothing.

RF4315AB-Pro can also test the inspiratory resistance of the sample.

Scope of application: Medical protective masks, daily protective masks, disposable respirators, half-mask respirators, full-face respirator, protective clothing, melt-blown cloth, etc.
