Product Design Meets Standards: GB 2626-2019 Respiratory protection Self-priming filter anti-particulate respirator GB 19082-2009 Technical requirements for medical disposable protective clothing GB 19083-2010 Technical requirements for medical protective masks GB/T 32610-2016 Technical specifications for daily protective masks YY 0469-2011 Medical surgical mask YY/T 0969-2013 disposable medical mask EN1822-3:2009 High-efficiency air filter (sub-high-efficiency, high-efficiency, ultra-high-efficiency) Part 3: Filter paper test ISO 29463-3:2011 High efficiency air filter and filter material Part 3: Filter paper test IEST-RP-CC021.3:2009 HEPA and ULPA filter material test JG/T22-1999 General ventilation air filter performance test method ANSI/ASHRAE 52.2-2012 General ventilation air filter diameter gauge efficiency test method EN779-2012 (Air filters for general ventilation-Determination of filtration performance) JISB9908-2011 (Test methods for air filter devices and electric air cleaners for ventilation). Main Feature: 1. The pressure difference measurement adopts imported brand high-precision pressure difference transmitter to accurately measure the resistance of the sample. 2. The efficiency test uses two well-known brand laser particle counters to detect the upstream and downstream particle concentration of the sample at the same time to ensure the authenticity and accuracy of the upstream and downstream use of the sample 3. The fogging system adopts Laskin nozzles, and the release of polydisperse particle size (monodisperse particle size is optional), and the fogging concentration adjustment is fast and stable 4. Touch screen control, simple and intuitive operation 5. The test result is automatically calculated and displayed by the system and printed out 6. Data port: external memory card, data can be exported, no need to worry about data loss The Main Technical Parameters: 1. The test flow range is 5～100L/min (standard condition 32L/min), ±1% 2. Test sample size: 100cm 2, various test fixtures can be customized according to customer requirements. 3. Resistance test: measuring range 0～1500Pa, accuracy up to ±0.025, automatic return to "0" function 4. Efficiency test: the efficiency range is 0～99.999%, and the penetration rate is 0.001%. 5. Test particle size: 0.1, 0.15, 0.2, 0.25, 0.3, 0.5, 1.0, 2.0, 5.0, 10.0 μm (select the corresponding sensor according to customer requirements) 6. Fog dust source: salt aerosol (NaCL, KCL,) oil aerosol (DEHS, DOP, PAO) and PSL (select when ordering) 7. Test time: resistance is tested separately for 10s, efficiency and resistance are tested at the same time for 60s 8. Temperature: 0～50C°, ±0.5C°. Humidity: 0～100%RH, ±3%. 9.
