What brand of particle counter is used in protective equipment workshop?

With the gradual tightening of market supervision, every production enterprise has stricter requirements on product quality. In the severe epidemic period, masks have become a necessity for us to go out. Just like the mobile phone we often hold in our hands, we also pay more attention to the quality of masks. Medical surgical masks can effectively prevent the spread of pathogenic bacteria and protect healthy people. If we want to sell our masks to other countries, we need to have corresponding standards and carry out various tests to make them meet export standards. Taking mask meltblown fabric as an example, the detection of meltblown fabric usually includes the following tests, such as filtration efficiency, filtration resistance test, submicroscopic morphology analysis, extrusion swelling performance test, dynamic viscoelasticity test, differential scanning calorimetry (DSC) analysis, etc.

The filter efficiency detector of mask meltblown cloth particles is used to detect the filter efficiency of disposable medical masks, medical surgical masks, civil masks and other daily protective masks, and can be used to evaluate the protective effect of masks. It can be used to test the particle filtration efficiency of masks, filter materials, etc. In medical equipment inspection offices, centers for disease control and prevention, hospitals, high-efficiency filter manufacturers and mask manufacturers.

Three-channel high-precision hand-held laser dust particle counter HPC300A was designed by Shenzhen Sainawei according to international standards ISO 14644- 1 and GMP. Available in Chinese and English versions, it can detect three kinds of particle sizes at the same time (users can set the particle sizes to be detected at will), and it can be downloaded at high speed through USB interface. It can be widely used in clean workshop environment detection, indoor environment detection and filtration efficiency analysis and test in electronic industry and pharmaceutical industry.
