Taw qhia:
Lub hauv paus ntsiab lus ntawm turbidity sensor yog ua los ntawm kev sib xyaw infrared nqus thiab tawg txoj kev teeb. Txoj kev ISO7027 tuaj yeem siv los txiav txim siab tsis tu ncua thiab raug txiav txim siab tus nqi turbidity. Raws li ISO7027 infrared ob-scattering lub teeb tshuab tsis cuam tshuam los ntawm chromaticity los txiav txim siab sludge concentration tus nqi. Kev tu tus kheej tuaj yeem xaiv tau raws li qhov chaw siv. Cov ntaub ntawv ruaj khov, txhim khu kev qha ua haujlwm; built-in self-diagnosis muaj nuj nqi kom paub meej cov ntaub ntawv; yooj yim installation thiab calibration.
Daim ntawv thov:
Turbidity xyuas cov dej los ntawm cov dej ua haujlwm, kev saib xyuas dej zoo ntawm cov kav dej hauv nroog; kev lag luam txheej txheem dej zoo xyuas, circulating dej txias, activated carbon lim effluent, membrane filtration effluent, thiab lwm yam.
