1 Product introduction

ZR - 1002 masks particle detector is protective effect on volume of 500 l self-purification test chamber was gb head mould, will be waiting for inspection masks worn on the head, by any quality median diameter was (0.6 + / - 0.050 mu m, in the salt concentration of 20 mg/m3 aerosols and mass median diameter was (0.3 + 0.050) microns, concentration of 20 mg/m3 of oily aerosol net input from the test chamber, head do sine curve simulation breath, before using the photometer upstream and downstream sampling detection mask and mask after salt aerosols and oily aerosol concentration,To evaluate the protection effect of respirator particles.The mask can be worn on the national head mold to automatically detect respiratory resistance.It is applicable to the detection of the protective effect of respirator, filter material and other particulate matter by medical instrument inspection institute, center for disease control and prevention, hospital, hepa filter manufacturer, mask r&d and manufacturer.

2 Scope of application

It is applicable to the detection of the protective effect of respirator, filter material and other particulate matter by medical instrument inspection institute, center for disease control and prevention, hospital, hepa filter manufacturer, mask r&d and manufacturer.

3 Sampling standard

GB/T6165-2008 Performance test methods for hepa filters - technical requirements and test methods for efficiency and resistance of particulate matter protection

GB2626-2019 Respiratory protective self-absorption filter respirator against particulate matter

GB/T 32610-2016 Technical requirements for daily protective masks

4 Main features

 Respirator particle protection and respiratory resistance detection integrated design, one machine multi-purpose

 The self-cleaning test chamber is equipped with operation gloves to facilitate the replacement of the inspection mask.

 Three kinds of head - mode compatibility design, head - mode plug and play, convenient replacement.

 The salt and oil aerosol generator can be used to control the concentration of particulate matter.

 The large touch display is designed to automatically display the respiratory flow curve and automatically calculate the protection effect of particulate matter.

 The whole process of particle leakage prevention design, to protect the safety of the experimenters.

 Photometer long life laser light source, high precision photomultiplier detection.

 Photometer working time statistics, automatic indication of cleaning time.

 The use time of hepa filter is automatically counted, which prompts the replacement of hepa filter.

 Historical data can be exported via a U disk or printed via an embedded printer.
