Kuti muzindikire kutuluka kwa HEPA Fyuluta, imadziwika bwino kugwiritsa ntchito aerosol photometer poyesa. Lero titengaZR-6012 Aerosol Photometermonga chitsanzo kukudziwitsani mfundo yodziwira.

Aerosol Photometer idapangidwa potengera mfundo ya Mie kumwaza, yomwe imatha kuzindikira tinthu tating'onoting'ono ta 0,1 ~ 700 μm. Mukazindikira kutayikira kwa fyuluta yochita bwino kwambiri, iyenera kugwirizana nayoJenereta ya Aerosol . Jenereta imatulutsa tinthu tating'onoting'ono tosiyanasiyana tosiyanasiyana, ndiyeno gwiritsani ntchito sikani ya photometer kuti muwone fyulutayo. Kutayikira kwa fyuluta yochita bwino kwambiri kumatha kuzindikirika Motere.

Kuthamanga kwa mpweya kumaponyedwa ku chipinda chobalalitsira kuwala, ndipo tinthu tating'onoting'ono timabalalika ku chubu cha photomultiplier. Kuwala kumasinthidwa kukhala chizindikiro chamagetsi mu chubu cha photomultiplier. Pambuyo pakukulitsa ndi digitization, imawunikidwa ndi microcomputer kuti idziwe kukula kwa kuwala kobalalika. Kupyolera mu kufananitsa chizindikiro, tikhoza kupeza ndende ya particulate mu otaya. Ngati pali phokoso la alamu (kuchuluka kwa kutayikira kumaposa 0.01%), kumasonyeza kuti pali kutayikira.

Tikazindikira kutayikira kwa fyuluta yochita bwino kwambiri, tiyenera kugwirizana nayojenereta ya aerosol . Imatulutsa tinthu tating'onoting'ono tosiyanasiyana tosiyanasiyana, ndipo imasintha ndende ya aerosol momwe imafunikira kuti ndende yakumtunda ifike 10 ~ 20ug / ml. Kenako aerosol Photometer idzazindikira ndikuwonetsa kuchuluka kwa tinthu tating'ono.
