NovaStar, QT141, Medical Face Mask Synthetic Blood Penetration Resistance Tester, 110-240V, Touch Screen English Display (New)

NovaStar, QT141, Medical Face Mask Synthetic Blood Penetration Resistance Tester, 110-240V, Touch Screen English Display

Description

  1. Overview
    1. QT141 medical face mask synthetic blood penetration resistance tester is used to determine the resistance of medical protective masks to penetration by synthetic blood at different test pressures and can also be used to determine the resistance to blood penetration of other coating materials.
    2. The device is used for anti-synthetic blood penetration of medical surgical masks, and mainly used in the field of medical protection products. It can also be used for other textile coating material determination.
  2. Standards
    1. ISO 22609:2004: Clothing for protection against infectious agents — medical face masks — test method for resistance against penetration by synthetic blood (fixed volume, horizontally projected)
    2. YY0469-2011: Medical surgical masks
    3. GB19083-2010: Technical requirements for medical protective masks
    4. YY/T0691-2008: Clothing for protection against infectious agents-medical face masks-test method for resistance against penetration by synthetic blood (fixed volume, horizontally projected)
    5. EN 14683:2019: Medical face marks – requirements and test methods
    6. ASTM F1862-07: Standard test method for resistance of medical face masks to penetration by synthetic blood (horizontal projection of fixed volume at a known velocity)
  3. Technical Parameters

    7. Dimensions: about 650 mm × 200 mm × 350 mm
    8. Power: AC (110~240) V, 50 Hz
    9. Display: touch screen in English display
  4. Product Features
    1. Reserve the test target area without destroying the sample, and distribute synthetic blood in the sample target area.
    2. A special jet device with constant pressure can spray a certain volume of synthetic blood in a controlled time.
    3. It can fully simulate the corresponding injection rate to test under the average blood pressure of the human body at 10.7 kPa, 16 kPa, 21.3 kPa.
    4. The fixed target plate can block the high pressure part of the injected liquid flow to allow the steady flow to be sprayed to the sample, increasing the accuracy and repeatability of liquid spraying speed.
