Author:QINSUN Released in:2023-08 Click:109

The mask particle filtration efficiency tester is a test equipment independently developed and produced by qisnun Precision Electromechanical Technology Co., Ltd. It uses an aerosol generator to generate a certain gas concentration, then uses a photometer to measure the gas concentration for particle size detection before and after breathing. It is used to test the protective effect and filtration efficiency of daily protective and medical masks and respirators on particles.

Applicable standards:

GB2626, GB32610-2016, YY0469-2011, GB19083-2010

Main parameters:

1. The particle size distribution of the aerosol generator: 0.02-2μm.

2. Aerosol concentration detection device:

Concentration ≤ 30mg/m3, detection dynamic range: 0.0-999.9mg/m3, accuracy 1 %,

Sampling frequency:≥1 time/min, and equipped with an aerosol generator charge neutralization device.

3. Test head model: national standard head model.

4. Respiratory simulator: sinusoidal airflow, particle protection effect tester for masks, frequency 20 times/min, respiratory rate (30±1) L/min.

5. Filtration efficiency detection range: 0-99.999%.
