DOS-1707 ppm level portable Desktop Dissolved Oxygen Meter ndi imodzi mwa ma electrochemical analyzers omwe amagwiritsidwa ntchito mu labotale komanso chowunikira chanzeru kwambiri chopangidwa ndi kampani yathu. Ikhoza kukhala ndi DOS-808F Polagraphic Electrode, yomwe imayesa kuchuluka kwa ppm level automatic. Ndi chida chapadera chomwe chimagwiritsidwa ntchito poyesa kuchuluka kwa mpweya m'madzi ophikira boiler, madzi oundana, zimbudzi zoteteza chilengedwe ndi mafakitale ena.

Mpweya wosungunuka ndi muyeso wa kuchuluka kwa mpweya wa mpweya womwe uli m'madzi. Madzi abwino omwe angathandizire zamoyo ayenera kukhala ndi mpweya wosungunuka (DO).
Mpweya wosungunuka umalowa m'madzi ndi:
kuyamwa mwachindunji kuchokera mumlengalenga.
kuyenda mofulumira kuchokera ku mphepo, mafunde, mafunde kapena mpweya wozizira.
photosynthesis ya zomera zam'madzi monga chotulukapo cha njirayi.
Kuyeza mpweya wosungunuka m'madzi ndi kuchiza kuti pakhale kuchuluka koyenera kwa mpweya wosungunuka, ndi ntchito yofunika kwambiri pa ntchito zosiyanasiyana zochizira madzi. Ngakhale kuti mpweya wosungunuka ndi wofunikira kuti uthandize moyo ndi njira zochizira, ukhozanso kukhala woopsa, zomwe zimayambitsa okosijeni yomwe imawononga zida ndikuwononga zinthu. Mpweya wosungunuka umakhudza:
Ubwino: Kuchuluka kwa DO kumatsimikizira ubwino wa madzi ochokera ku gwero. Popanda DO yokwanira, madzi amakhala onyansa komanso osavulaza omwe amakhudza ubwino wa chilengedwe, madzi akumwa ndi zinthu zina.
Kutsatira Malamulo: Kuti atsatire malamulo, madzi otayidwa nthawi zambiri amafunika kukhala ndi kuchuluka kwa DO asanatulutsidwe mumtsinje, nyanja, mtsinje kapena m'madzi. Madzi abwino omwe angathandize moyo ayenera kukhala ndi mpweya wosungunuka.
Kuwongolera Njira: Kuchuluka kwa DO ndikofunikira kwambiri powongolera kuchiza madzi otayika mwachilengedwe, komanso gawo losefera madzi akumwa. Mu ntchito zina zamafakitale (monga kupanga magetsi), DO iliyonse imawononga kupanga nthunzi ndipo iyenera kuchotsedwa ndipo kuchuluka kwake kuyenera kulamulidwa bwino.
