NovaStar, QT132, Tester for Filtering Efficiency and Protective Effect of Mask Particulate Matter, 7-inch Touch Screen, Salt and Oil Tests (New)

NovaStar, QT132, Tester for Filtering Efficiency and Protective Effect of Mask Particulate Matter, 7-inch Touch Screen, Salt and Oil Tests

Description

  1. Scope Of Application
    1. Suitable for rapid, accurate and stable detection of particulate filtering efficiency and protective performance of various medical and daily protective masks, respirators, etc.
  2. Related Standards
    1. GB / T 19083-2010 technical requirements for medical protective masks 5.4 filtration efficiency
    2. YY / T 0469-2011 medical surgical masks 5.6.2 particle filtration efficiency
    3. GB / T 32610-2016 daily protective mask technical specification appendix B
    4. GB 2626-2019 respiratory protection self-priming filtering anti-particulate respirator 6.3 filtration efficiency
    5. GB 19082-2009 technical requirements for disposable medical protective clothing 5.7 filtration efficiency
    6. EN 1822-3: 2012
    7. EN 149-2001
    8. EN 14683: 2005 IEST-RP-CC021.1 NIOSH 42 CFR part 84, etc.
  3. Instrument Characteristics
    1. The resistance difference of the filter material will be obtained through the static pressure ring of its upstream and downstream test chambers, and a high-precision imported brand pressure difference transmitter will be used to ensure the accuracy and stability of the pressure difference.
    2. Use high-precision particle counter to sequentially detect the concentration of upstream and downstream particles to ensure accurate, stable, fast and effective sampling.
    3. The system test flow mainly provides dry and clean compressed air from the outside. There is a voltage stabilization and flow stabilization device installed inside to ensure the stability of the detection flow, and an automatic control system is adopted, which is simple, fast and stable.
    4. Using the collision multi-nozzle design, salt and oil tests can be performed on the same instrument to ensure fast and stable fog concentration adjustment.
    5. Equipped with a 7-inch touch screen, the test results are displayed directly, and the user can choose to directly record or save the data.
    6. The user only needs to place the filter paper in the fixture and press the button. After adjusting the flow, the system will automatically test the resistance and filtration efficiency through the controller (PLC). The whole process is simple, fast and efficient.
