Khoom Description
Lub fluorescence dissolved oxygen analyzer yog raws li lub hauv paus ntsiab lus quenching ntawm cov khoom tshwj xeeb hauv physics rau active fluorescence. Cov tshuaj fluorescent nyob rau hauv pem hauv ntej kawg ntawm lub sensor yog ib tug tshwj xeeb platinum metalloporphyrin composite nrog ib tug polyester foil uas tso cai rau cov roj mus dhau. Qhov saum npoo yog coated nrog lub teeb dub thaiv cov khoom kom tsis txhob cuam tshuam los ntawm lub hnub ci thiab lwm yam tshuaj fluorescent hauv dej. Lub teeb ntsuab modulated illuminates cov tshuaj fluorescent kom excite nws thiab emit liab teeb. Vim lub quenching nyhuv ntawm oxygen molecules, lub sij hawm thiab kev siv ntawm exciting liab teeb yog inversely proportional rau cov concentration ntawm oxygen molecules. Peb siv lub teeb liab qhov chaw synchronized nrog lub teeb ntsuab raws li kev siv, ntsuas cov theem sib txawv ntawm lub teeb liab zoo siab thiab lub teeb siv, thiab muab piv nrog tus nqi ntsuas sab hauv los xam cov concentration ntawm oxygen molecules. Tom qab them nyiaj kub, qhov kawg tus nqi yog cov zis. Fluorescence dissolved oxygen meters yog siv rau hauv kev kho dej khib nyiab, suav nrog kev tswj cov tso tsheb hlau luam, cov tso tsheb hlau luam aeration, aerobic / anaerobic digestion tanks, thiab kev tshawb nrhiav dej. Hauv cov txheej txheem kev lag luam: kev saib xyuas dej zoo ntawm kev tsim cov dej ntws, cov dej ntws, thiab lwm yam. Tshawb xyuas cov dej ib puag ncig hauv cov dej ntws, pas dej, dej hiav txwv, thaj chaw nuv ntses, thiab aquaculture.
