T9000 NwsCODcr Dej Zoo On-line Tsis Siv Neeg Saib Xyuas
Product Principple
Cov qauv dej, cov tshuaj poov tshuaj dichromate digestion, nyiaj sulfate tov (silver sulfate li catalyst tuaj yeem ntxiv rau oxidize linear aliphatic tebchaw zoo dua) thiab cov concentrated sulfuric acid sib tov rau 175 ℃. Cov xim ntawm cov organic tebchaw hauv dichromate ion oxidation tov yuav hloov. Lub analyzer kuaj pom cov xim hloov thiab hloov cov kev hloov pauv mus rau COD tus nqi ces tso tawm tus nqi.Tus nqi ntawm dichromate ion noj yog sib npaug rau cov nyiaj oxidizable organic teeb meem, uas yog COD.
Technical Parameters:
| Tsis muaj. | Lub npe | Technical Specifications |
| 1 | Daim Ntawv Thov Ntau | Haum rau cov dej khib nyiab nrog COD hauv thaj tsam ntawm 10 ~5,000mg / L thiab chloride concentration tsawg dua 2.5g / L Cl-. Raws li cov neeg siv khoom xav tau tiag tiag, nws tuaj yeem txuas mus rau cov dej khib nyiab nrog cov tshuaj chloride tsawg dua 20g / L Cl-. |
| 2 | Kev sim | Potassium dichromate digestion ntawm kub kub, colorimetric txiav txim |
| 3 | Kev ntsuas ntau | 10 ~ ib5,000mg / L |
| 4 | Tsawg txwv ntawm Kev Tshawb Fawb | 3 |
| 5 | Kev daws teeb meem | 0.1 |
| 6 | Qhov tseeb | ± 10% lossis ± 8mg / L (Nqa tus nqi loj dua) |
| 7 | Rov ua dua | 10% lossis 6mg / L (Nqa tus nqi loj dua) |
| 8 | Zero Drift | ± 5mg / L |
| 9 | Span Drift | ± 10% |
| 10 | Kev ntsuas lub voj voog | Yam tsawg kawg 20 feeb. Raws li cov qauv dej tiag tiag, lub sijhawm zom zaub mov tuaj yeem teem caij los ntawm 5 mus rau 120 feeb. |
| 11 | Lub sijhawm ua piv txwv | Lub sij hawm ncua sij hawm (kho tau), ib teev lossis ntsuas ntsuas hom tuaj yeem teeb tsa. |
| 12 | Calibration lub voj voog | Tsis siv neeg calibration (1-99 hnub adjustable), raws li cov qauv dej tiag tiag, phau ntawv calibration tuaj yeem teeb tsa. |
| 13 | Kev kho lub voj voog | Lub sijhawm tu ncua yog ntau tshaj ib hlis, txog 30 feeb txhua zaus. |
| 14 | Tib neeg-tshuab ua haujlwm | Kov npo zaub thiab kev qhia tswv yim. |
| 15 | Kev tiv thaiv tus kheej | Cov xwm txheej ua haujlwm yog kuaj tus kheej, qhov txawv txav lossis lub zog tsis ua haujlwm yuav tsis poob cov ntaub ntawv. Tsis siv neeg tshem tawm cov residual reactants thiab rov pib ua haujlwm tom qab rov pib dua lossis tsis muaj zog. |
| 16 | Cov ntaub ntawv khaws cia | Tsis pub tsawg tshaj li ib nrab xyoo cov ntaub ntawv khaws cia |
| 17 | Input interface | Hloov kom muaj nuj nqis |
| 18 | Output interface | Ob tug RS485 ibdigital tso zis, Ib qho 4-20mA analog tso zis |
| 19 | Cov xwm txheej ua haujlwm | Ua haujlwm hauv tsev; kub 5-28 ℃; txheeb ze humidity ≤90% (tsis muaj condensation, tsis muaj dew) |
| 20 | Kev siv hluav taws xob | AC230 ± 10% V, 50 ~ 60Hz, 5A |
| 21 | Qhov ntev | 355×400×600(mm) |
