T9008 BOD Dej Zoo Hauv Online Tsis Siv Neeg Saib Xyuas
Cov Ntsiab Cai Khoom:
Dejqauv, potassium dichromate digestion solution, silver sulfate solution (silver sulfate ua ib qho catalyst los koom nrog tau zoo dua cov roj sib xyaw ncaj nraim oxide) thiab sulfuric acid sib tov yog rhuab rau 175 ℃, dichromate ion oxide kua ntawm cov organic matter tom qab hloov xim, analyzer los ntes cov kev hloov xim, thiab qhov kev hloov ntawm kev hloov mus rau hauv BOD tus nqi tso zis thiab kev noj ntawm dichromate ion cov ntsiab lus ntawm oxidizable organic matter ntau.
Cov Kev Ntsuas Kev Txawj:
| Tsis yog. | Lub Npe | Cov Kev Ntsuas Kev Txawj |
| 1 | Daim Ntawv Thov Ntau Yam | Cov khoom no yog tsim rau cov dej khib nyiab uas muaj cov pa oxygen xav tau hauv qhov ntau ntawm 10 ~2000mg/L thiab chloride concentration qis dua 2.5g/L Cl-. Nws tuaj yeem nthuav dav mus rau cov dej khib nyiab nrog chloride concentration qis dua 20g/L Cl- raws li cov neeg siv khoom xav tau tiag tiag. |
| 2 | Cov Kev Ntsuas | Potassium dichromate tau zom ntawm qhov kub siab thiab kev txiav txim siab xim. |
| 3 | Kev ntsuas ntau yam | 10~2000mg/L |
| 4 | Qhov txwv qis dua ntawm kev tshawb pom | 3 |
| 5 | Kev daws teeb meem | 0.1 |
| 6 | Kev raug | ±10% los yog ±8mg/L (Siv tus nqi loj dua) |
| 7 | Rov ua dua tau | 10% los yog6mg/L (Siv tus nqi loj dua) |
| 8 | Zero Drift | ±5mg/L |
| 9 | Span Drift | 10% |
| 10 | Kev ntsuas voj voog | Yam tsawg kawg yog 20 feeb. Nyob ntawm seb cov dej piv txwv tiag tiag, lub sijhawm zom zaub mov tuaj yeem teeb tsa tau txij li 5 txog 120 feeb.. |
| 11 | Lub sijhawm kuaj | Lub sijhawm sib txawv (kho tau), teev sib xyaw lossis hom ntsuas qhov ua rau tuaj yeem teeb tsa. |
| 12 | Lub voj voog kho kom raug | Kev ntsuas tsis siv neeg (1-99 hnub hloov kho tau), raws li cov qauv dej tiag tiag, kev ntsuas tes tuaj yeem teeb tsa. |
| 13 | Kev saib xyuas lub voj voog | Lub sijhawm txij nkawm yog ntau tshaj ib hlis, kwv yees li 30 feeb txhua zaus. |
| 14 | Kev ua haujlwm ntawm tib neeg thiab tshuab | Kov npo zaub thiab cov lus qhia nkag. |
| 15 | Kev tiv thaiv tus kheej kuaj xyuas | Kev ua haujlwm yog tus kheej kuaj mob, qhov tsis zoo lossis lub zog tsis ua haujlwm yuav tsis poob cov ntaub ntawv. Tshem tawm cov tshuaj reactants seem thiab rov ua haujlwm tom qab rov pib dua tsis zoo lossis lub zog tsis ua haujlwm. |
| 16 | Kev khaws cov ntaub ntawv | Tsis pub tsawg dua ib nrab xyoo khaws cov ntaub ntawv |
| 17 | Kev sib txuas lus ntawm cov tswv yim | Hloov qhov ntau |
| 18 | Cov zis interface | Ob tug RS485Cov zis digital, Ib qho 4-20mA analog tso zis |
| 19 | Cov Cai Ua Haujlwm | Ua haujlwm sab hauv tsev; kub 5-28 ℃; av noo txheeb ze ≤ 90% (tsis muaj condensation, tsis muaj dew) |
| 20 | Kev Muab Hluav Taws Xob thiab Kev Siv Hluav Taws Xob | AC230±10%V, 50~60Hz, 5A |
| 21 | Qhov Loj | 355×400 ×600 (hli) |
