Mask ya bacteri yo kuyungurura neza (BFE)

Ibipimo byingenzi byerekana ibipimo bya DRK-1000 mask ya Bacterial Filtration Efficiency (BFE) ntabwo yujuje gusa ibisabwa byumugereka B BIKORESHEJWE BIKORESHEJWE BFE (BFE) Uburyo bwikizamini b.1.1.1 mubisabwa tekiniki kubuvuzi bwa masiki yo kubaga yy0469-2011, Kandi kandi ijyanye n'ibisabwa na Sosiyete y'Abanyamerika ishinzwe gupima ibikoresho ASTMF2100, ASTMF2101, Ibipimo by’iburayi EN14683, kandi hashingiwe ku guhanga udushya, gukoresha inzira ya gazi ebyiri icyarimwe uburyo butandukanye bwo gutoranya, kunoza ukuri kw'icyitegererezo. Irakwiriye kwipimisha imikorere ya bagiteri yo kuyungurura masike nishami rishinzwe kugenzura metrologiya, ibigo byubushakashatsi bwa siyansi, abakora mask nandi mashami bireba.

Ibiranga ibicuruzwa:

1, Sisitemu yo gupima igitutu kibi, kugirango umutekano wabakoresha;

2, Umuvuduko mubi winama yubatswe muri pompe ya peristaltike, A, B inzira ebyiri inzira esheshatu Andersen; Ingano ya pompe ya pisitike irashobora gushyirwaho;

3, Microbial aerosol generator ya bacteri nijoro spray itemba irashobora gushyirwaho, ingaruka nziza ya atomisation;

4, Gushyiramo umuvuduko mwinshi inganda za microcomputer; 10.4 “urwego rwo mu rwego rwo hejuru rugaragaza ibara ryerekana ibara;

5, USB interineti, shyigikira U disiki yoherejwe;

6, Inama y'Abaminisitiri yubatswe mu mucyo mwinshi; Yubatswe muri sisitemu yo gukingira, kurinda umutekano wumukoresha;

7. Igice cy'imbere cy'inama y'abaminisitiri gikozwe mu byuma bitagira umwanda muri rusange, kandi igice cyo hanze cyatewe isahani ikonje ya plastike ikonje. Imbere n'inyuma byashyizwe hamwe kandi birinda umuriro.

8, Imbere yimbere yubwoko bwikirahure, byoroshye kureba imikorere yabakozi ba laboratoire;

9, Ikurwaho ryakuweho, uburebure bwikurikiranya burashobora guhinduka; Shyigikira kandi wimure ibice bibiri.
