Introduction:
The automatic filter material tester can simulate the actual use environment of the mask or filter material, and test the filtration efficiency and filtration resistance based on the oil mist and salt mist methods required by the standard.
The test parameters meet the requirements of the test methods in NIOSH 42 CFR Part 84 and GB / T 2626 standards.
In addition, the automatic filter tester can also test the permeability of the filter material, the test pore size: 1/1, 1/2, 1/4, 1/8;
Test material: layered mask or filter material;
Test methods: oil mist test and salt mist test;
Test parameters: filtration efficiency, filtration resistance, etc .;
The automatic filter tester can accurately evaluate the filtering performance of masks or filter materials, and provide data basis for the research and development of new filter materials, product quality control, and material performance verification.
Standards:
NIOSH 42 CFR Part 84 Respiratory protective device technical requirements;
GB/T 2626 Respiratory protective equipment-self-priming filter type anti-particulate respirator.
