Respirator Protective Clothing Particle Filtration Efficiency Test Equipment
Respirator Protective Clothing Particle Filtration Efficiency Test Equipment
Product overview:
Particle filtration efficiency testing equipment is used to test the filtration efficiency of particulate matter for daily protective masks and medical masks, and determine the obstruction performance of ordinary fabrics and medical protective masks against the constant flow of airflow.
It is widely adopted by medical device inspection center, safety protection inspection center, labor protection inspection center, drug inspection center, disease prevention and control center, textile testing center, hospital, mask manufacturing enterprises, etc.
Technical Parameters:
1. Range: (10 ~ 100) L / min, order of accuracy 2.5.
2. Filter efficiency test detection range: (0.001 ~ 99.999)%.
3. Filter efficiency test sampling frequency: 1-9999 times / min, can be set arbitrarily.
4. Filtration efficiency test particle concentration: (0.001 ~ 200) mg / m3.
5. Differential pressure transducer range: 0 ~ 1000 pa.
6. Median diameter: salt particles (0.075 ± 0.02) μ m, oil particles (0.185 ± 0.02) μ m. Geometric criteria for particle size distribution
Deviation: salt particles ≤ 1.86, oil particles ≤ 1.60. Dynamic detection range: 0.001-100mg / m3, accuracy 1%.
7. Test area: 100 cm2.
8. Aerosol agent: sodium chloride (optional with DOP, DEHS, wax oil, corn oil).
9. Aerosol concentrations: 12-20 mg / m3 (salty), 50-200 mg / m3 (oily).
10. Power supply: AC220V 50Hz.
11. Control mode: touch screen computer control, through the touch screen or mouse operation. Operation is simple and intuitive.
12. After the test is completed, PDF test reports are automatically generated and test data can be exported without fear of data loss.
13. Simple operation: The user only needs to put the object to be tested into the fixture, press the button, and the system adjusts the test flow through the controller (PLC).
Automatic detection of filtration efficiency, the whole process is simple, fast and efficient.
