Ukuze kutholwe ukuvuza kwesihlungi se-HEPA, kwaziwa kahle ukusebenzisa i-aerosol photometer ukuhlola. Namuhla, SizothathaI-ZR-6012 Aerosol Photometernjengesibonelo ukwethula umgomo wokutholwa.

I-Aerosol Photometer yakhelwe ngokusekelwe kumgomo we-Mie scatter, ongathola ngempumelelo izinhlayiya ezisukela ku-0.1 ~ 700 μm. Lapho ithola ukuvuza kwesihlungi esisebenza kahle kakhulu, idinga ukusebenzisana nayoIjeneretha ye-aerosol . Ijeneretha ikhipha izinhlayiya ze-aerosol ezinosayizi abahlukahlukene, bese isebenzisa inhloko yokuskena ye-photometer ukuze ithole isihlungi. Izinga lokuvuza kwesihlungi esisebenza kahle kakhulu singatholwa Ngale ndlela.

Ukugeleza komoya kumpontshelwa egumbini lokuhlakaza ukukhanya, futhi izinhlayiya ekugelezeni zihlakazeke kushubhu ye-photomultiplier. Ukukhanya kuguqulwa kube isignali kagesi kushubhu ye-photomultiplier. Ngemuva kokukhulisa nokwenza idijithali, ihlaziywa yi-microcomputer ukuze kutholwe ukuqina kokukhanya okuhlakazekile. Ngokuqhathanisa isignali, singathola ukugxila kwe-particle ekugelezeni. Uma kunomsindo we-alamu (izinga lokuvuza lingaphezu kuka-0.01%), libonisa ukuthi kukhona ukuvuza.

Lapho sithola ukuvuza kwesihlungi esisebenza kahle kakhulu, sidinga ukubambisana nakhoijeneretha ye-aerosol . Ikhipha izinhlayiya ze-aerosol ezinosayizi abahlukene, futhi ilungisa ukugxiliswa kwe-aerosol njengoba kudingekile ukwenza ukugxiliswa komfula kufinyelele ku-10 ~ 20ug / ml. Khona-ke i-photometer ye-aerosol izobona futhi ibonise ukugxila kwe-particle mass.
