【Scope of Application】
Respiratory mask leakage testing is used for KN95 masks, protective clothing, daily protective masks, self-priming filtering particulate respirators, etc., to test the filtration efficiency and protective efficacy of respiratory masks and protective masks.
【Compliant Standards】
1. Testing standards reference:
2. GB 2626 Respiratory protection - Self-priming filtering anti-particulate respirators
3. EN149:2001+A1:2009 Respiratory protective devices - Filtering half masks to protect against particles - Requirements, testing, marking
4. GB/T 29511 Protective clothing - Chemical protective clothing against solid particulates
【Instrument Features】
1. Efficiency Detection: Uses imported high-precision photometer from the renowned TSI brand to detect concentration inside the chamber and inside the facepiece, ensuring sampling is accurate, stable, fast, and effective.
2. Testing Chamber: The chamber is sufficiently large, with ample observable range to accommodate standard required movements (person upright, treadmill exercise, turning in place, etc.).
3. Aerosol Generation: Capable of performing salt and oil tests on the same instrument, with automatic switching, eliminating manual operation, ensuring fast and stable aerosol concentration adjustment.
4. Test Results: Equipped with professional computer software; results are displayed directly on the interface, can be printed, and data is saved.
