GL-1000 Mask particle filtration efficiency tester
Product overview
Particle filtration efficiency tester 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 - self suction filtration type particle respirator, GB 19083-2010 medical protective mask, and GB / T 32610-2016 daily protective mask.
Equipment composition and principle
The instrument is composed of Salt spray generator (Nacl), Oil mist generator (DOP), 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.
It 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 mask particles.
