Mask bacterial filtration performance (BFE) detector

Iimpawu eziphambili zentsebenzo ye-DRK-1000 imaski ye-Bacterial Filtration Efficiency (BFE) detector ayifezekisi kuphela iimfuno ze-APPENDIX B Bacterial Filtration Efficiency (BFE) Indlela yokuvavanya b.1.1.1 kwiiMfuno zobuGcisa kwiiMaski zoNyango lwezoNyango yy0469-2011, Kwaye ngokunjalo ngokuhambelana neemfuno ze-American Society for Testing Materials ASTMF2100, ASTMF2101, imigangatho ye-EN14683 yaseYurophu, kwaye kwesi siseko, ukuphuculwa kwezinto ezintsha, ukusetyenziswa kweendlela ezimbini zegesi ngexesha elifanayo lesampulu eyahlukileyo, ukuphucula ukuchaneka kwesampulu. Ilungele uvavanyo lokusebenza lwe-bacterial filtration ye-masks ngamasebe okuqinisekisa i-metrological, amaziko ophando lwenzululwazi, abavelisi bemaski kunye namanye amasebe afanelekileyo.

Iimpawu zeMveliso:

I-1, inkqubo yokuvavanya uxinzelelo olubi, ukuqinisekisa ukhuseleko lwabaqhubi;

2, Ikhabhathi yoxinzelelo olubi olwakhelwe ngaphakathi kwimpompo ye-peristaltic, A, B ezimbini iindlela ezintandathu kwinqanaba Andersen; Ubungakanani bempompo yePeristaltic inokusetwa;

I-3, iibhaktheriya ezikhethekileyo ze-aerosol generator iibhaktheriya zokutshiza ebusuku zingasetwa, isiphumo esihle se-atomization;

I-4, Ulawulo lwe-microcomputer olunesantya esiphezulu kwishishini; 10.4 “iscreen sombala wokuqaqamba okuphezulu kombala weshishini;

I-5, i-interface ye-USB, inkxaso yokudlulisa idatha yediski ye-U;

I-6, iKhabhinethi eyakhelwe-ngaphakathi ekukhanyeni okuphezulu ukukhanya; Iswitshi yokukhusela ukuvuza eyakhelwe-ngaphakathi, ukukhusela ukhuseleko lomsebenzisi;

7. Uluhlu lwangaphakathi lwekhabhinethi lwenziwe ngensimbi engenasici iyonke, kwaye umaleko wangaphandle utshizwe ngeplati egobileyo yeplastiki. Amaleko angaphakathi nangaphandle afakwe i-insulated kunye ne-flame retardant.

8, Front switch uhlobo umnyango iglasi, kulula ukujonga ukusebenza kwabasebenzi laboratory;

I-9, isibiyeli esisuswayo, ukuphakama kwesibiyeli kulungelelaniswa; Inkxaso kunye nokuhambisa ii-casters ezimbini.
