Turbidity, qhov taw qhia tseem ceeb ntawm cov dej ntshiab, qhia txog qib uas tshem tawm cov teeb meem hauv dej cuam tshuam lub teeb kis. Cov turbidity siab yuav qhia tau tias muaj ntau cov kab mob, cov organic teeb meem, los yog inorganic hais nyob rau hauv dej, ua rau muaj kev hem thawj rau tib neeg noj qab haus huv. Turbidity yog qhov taw qhia tseem ceeb rau kev ntsuam xyuas cov dej lim dej kom zoo thiab yog qhov tseem ceeb hauv kev kho dej haus, kev kho dej khib nyiab, kev tswj kev lag luam, thiab kev saib xyuas ib puag ncig.
Daim ntawv thov
Lub turbidimeter, tseem hu ua turbidity meter, yog siv nyob rau hauv cov nroj tsuag dej, fais fab nroj tsuag, industrial thiab mining lag luam, chaw soj nstuam, thiab daim ntawv thov teb los kuaj cov turbidity ntawm cov qauv dej. Turbidimeters tau siv dav hauv kev kho dej haus, kev kho dej khib nyiab, kev tswj cov txheej txheem kev lag luam (xws li papermaking, textiles, thiab zaub mov ua), kev saib xyuas ib puag ncig, tshuaj, tsim hluav taws xob, thiab dej haus kev lag luam rau lub sijhawm tiag tiag los yog kev soj ntsuam turbidity los xyuas kom muaj kev nyab xeeb ntawm dej thiab cov txheej txheem optimization. Cov cuab yeej no feem ntau yog ib qho tseem ceeb ntawm cov cuab yeej ntsuas uas xav tau rau cov nroj tsuag dej haus uas thov rau QS ntawv pov thawj.
Main Accuracy Indicators thiab Measurement Range
- Kev ntsuas ntau: 0-20, 20-200, 200-1000, 1000-2000, 2000-4000 NTU
- Kev daws teeb meem: 0.01, 0.1, thiab 1 NTU
- Qhov tseeb: 5% FS
- Ua haujlwm kub: 0-35 degree
- Fais fab mov: 220 ± 20V, 50HZ lossis 8 AA roj teeb
Turbidity, los yog qib ntawm cloudiness nyob rau hauv dej, yog tshwm sim los ntawm ib tug kab ntawm insoluble suspended teeb meem thiab colloidal tshuaj. Chav ntsuas ntsuas siv hauv ISO qauv yog FTU (turbidity unit), uas yog raws li NTU (turbidity ntsuas unit). Kev lag luam brewing siv EBC (extracorporeal membrane oxygenation), qhov twg 4 FTU=1 EBC.
Lwm cov chav ntsuas turbidity suav nrog JTU (Jackson Turbidity Unit) thiab ASBC (American Society of Brewing Chemists). Cov txheej txheem thoob ntiaj teb xws li ISO 7027 (infrared light method) thiab US EPA Method 180.1 (dawb lub teeb txoj kev) yog cov qauv ntsuas ntau.
