Introduction:
\nThis Mask Particle Filtering Efficiency Tester is designed for suitable testing 20%-99.9% grade filter efficiency test, according to international standards to test the filter material. The tester is designed to be compact and lightweight design, and during testing, just only the proper power supply and compressed air (anhydrous, no oil) is required to be used in laboratories, factories, etc.
\nThis equipment is used to test the filtration performance, filtration efficiency and filtration effect of the mask. At present, the mask is mainly divided into air filtration mask and air supply mask. This testing instrument is applicable to medical equipment testing center, safety protection testing center, labor protection testing center, drug testing center, disease prevention and control center, textile testing center, hospital, mask and respirator manufacturing enterprises, etc. It meets the technical requirements of GB 2626-2006 respiratory protective equipment \u2013 self suction filtration type particle respirator, GB 19083-2010 medical protective mask, and GB \/ T 32610-2016 daily protective mask.
\nPrinciple:
\nThe instrument is composed of NaCl generator, data acquisition software, testing product tooling device, concentration detector, filtered concentration detector, computer data calculation device, pressure regulating device and tooling pipeline testing auxiliary device.
\nIt is implemented by the photometer in the system to detect the concentration of mask before and after filtration, so as to detect the protective efficiency of respirator particles.
