Particle filtration efficiency tester(PFE)
Scope of application:
It is used to detect the filtration efficiency of particulate matter such as daily masks and filters.
It is applicable to medical equipment inspection center, safety protection inspection center, labor protection inspection center, drug inspection center, disease prevention and control center, hospital, mask and respirator manufacturer, etc.
Standards:
YY/T 2626-2019 Respiratory Protection Products
YY0469-2011 Medical Surgical Mask
GB / T 32610-2016 Technical Specifications for Daily Protective Masks
GB / T19083-2010 Technical Requirements for Medical Protective Masks
standard-SC-FT-1702D
NIOSH 42 CFR 84
Characteristics :
1. Using a cold aerosol generator to produce continuous and stable aerosol particles, convenient for filling the solution.
2. Use high-precision PM2.5 sensor to measure aerosol concentration.
3. The standard head mould is adopted to imitate the situation when a person wears a protective mask.
4, using a breathing simulator to simulate human breathing.
5. Anti-leakage design of the whole particle to protect the safety of laboratory personnel.
6. The test chamber is equipped with operating gloves to facilitate the replacement of the masks to be inspected.
7, three types of head mold compatibility design, head mold easy to replace.
8. Compatible with mask and respirator samples to test the particle protection and filtering efficiency.
9, aerosol type: salt particulate aerosol and oil particulate aerosol, sodium chloride (optional DOP, DEHS, paraffin oil, corn oil).
