Introduction of Mask Filter Tester
1. Standard: GB2626-2019 respiratory protection self-priming filter anti-particle respirator
2. Manufacturer: Dongguan Huanyi Instrument Technology Co., Ltd.
3. Applicable items
Mask Filter Tester is used to test the protective effect of daily protective masks and other types of masks on particulate matter.
4. Technical parameters:
4.1 Using aerosol generator to produce continuous and stable aerosol particles, convenient for filling solution.
4.2 Use high-precision PM2.5 sensor to measure aerosol concentration.
4.3 The whole process of particulate matter leakage prevention design, to protect the safety of laboratory personnel.
4.4 2 sets of aerosol generators: salt particulate aerosol generator and oil particulate aerosol generator. (Customer configuration)
4.5 Protective effect test chamber opened before] design, good sealing, equipped with operating gloves, easy to replace the mask to be inspected.
4.6 The protective effect test uses a standard head mold: 1 standard head mold, imitating the real situation of a person wearing a protective mask.
4.7 Protective effect Aerosol particles: concentration range of test chamber (20-30) mg / m3, adjustable settings, concentration fluctuation less than + 10%; particles generated by aerosol generator
Diameter distribution 0.02-2μm, mass median diameter: 0.6um salt particles, 0.3um oil particles.
sampling flow (1-2) L / min, sampling frequency: 20 times / min (1-9999 times / min can be arbitrarily set),
Dynamic detection (0.001-100) mg / m3 with 1% accuracy.
4.9 Protective effect The inhaled gas sampling tube is directly below the nostril (in the mouth).
4.10 Protective effect The breathing simulator is used to simulate human breathing.
4.11 Breathing simulator: sinusoidal airflow, frequency 20 times / min, respiratory flow control (30 + 1) L / min, respirator flow range: 0-40 L / min.
4.12 Control system: The computer controls the test process, automatically collects data, and configures special computers and test software.
4.13 Power: AC220V 50Hz
We not only have Mask Filter Tester but also many other mask testing equipment, such as respiratory resistance tester, universal material testing machine, etc.
