Mask Particle Filtration Efficiency Tester Test Head Model

The mask particle filtration efficiency tester is a testing 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. to detect particle size before and after breathing. 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 aerosol generator produces a particle size distribution: 0.02-2 μm.

2. Aerosol concentration detection device:

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

Sampling frequency: ≥1 fois/min, and equipped with a device for neutralizing the charge of the aerosol generator.

3. Trial head mold: natiSingle standard head mold.

4. Respiratory simulator: sinusoidal air flow, mask particle protection effect tester, frequency 20 times/min, respiratory flow (30±1) L/min.

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

As an enterprise integrating R&D, manufacturing, sales, training and service, Shanghai Fanbiao Textile Testing Technology Co., Ltd. is committed to continuously providing more testing instruments to the market and providing textiles, long-term testing. instruments for leather, combustion, automobile interior materials, environmental climate aging, masks, etc. can also accept non-standard customization. Targeted testing can be carried out according to customer requirements before purchasing for gensure that the instruments purchased are suitable.
