Photometer particle filtration tester

one. Photometometric particle filter tester product introduction:

Mask particulate matter filter efficiency and airflow resistance tester is composed of photometer, generator, air flowmeter, sealing box and corresponding pipeline.It can be used for detecting the filtration efficiency and resistance of masks, filter material and other particles in the textile testing center, mask research and development, and manufacturers.

two. Photometer particle filter tester implementation standard:

1.GB / T 32610-2016 Technical Specification for daily protective masks

2.GB 2626-2006 Respiratory protection equipment Self-priming filter anti-particulate matter respirator

3.GB 19082-2009 Technical requirements for medical disposable protective clothing

4.GB 19083-2010 Technical requirements for medical protective masks

5.TAJ 1001-2015 PM2.5 Protective mask

6.YY 0469-2011 Medical surgical mask

three. Test principle of mask filtration efficiency and resistance:

Fixed the mask and melt-blown cloth on the fixture, and the test air volume corresponds to the required filter speed.The aerosols produced by the aerosol generator are adjusted, then electrostatic neutralizing the aerosol, and then evenly mixed with the filtered test air,

Then enter the test area to penetrate the filter material.

To determine efficiency, one air shunt was drawn upstream and downstream of the mouth to hood.Using a luminometer, the concentration of diameter particles in the sampled airflow was measured through the upstream and downstream ratio, and then the measured efficiency was obtained.

In addition, you can also measure the filter material resistance and adjust the control flow rate
