Kev Taw Qhia
Kev tshuaj xyuas cov pa oxygen xav tau (COD) ib txwm xav tau cov khoom siv hauv chaw kuaj mob, cov tshuaj lom neeg (dichromate), thiab cov txheej txheem zom zaub mov ntev. Tab sis yog tias koj tuaj yeem saib xyuas COD, Biochemical Oxygen Demand (BOD), Total Organic Carbon (TOC), thiab turbidity tib lub sijhawm, hauv lub sijhawm tiag tiag, yam tsis muaj cov tshuaj reagents?
Lub Digital RS485 Output COD Sensor (Qauv CS6603CD) ua qhov no ua tau los ntawm kev siv thev naus laus zis Ultraviolet Absorption (UV254). Ntau cov organic sib xyaw nqus lub teeb UV ntawm 254 nm. Los ntawm kev ntsuas qhov absorbance ntawm qhov wavelength tshwj xeeb no, lub sensor txuas ntxiv suav cov nqi COD, BOD, thiab TOC sib npaug - txhua yam tsis muaj tshuaj lom neeg, tsis tas yuav npaj cov qauv, thiab tsis muaj kuab paug.
Lub sensor no kuj tseem muaj kev them nyiaj rau qhov turbidity, siv kev ntsuas sib cais los kho qhov cuam tshuam los ntawm cov khoom khov uas raug tshem tawm, thiab txhuam nws tus kheej los ntxuav kom tiv thaiv kev ua qias tuaj, kom ntseeg tau tias kev ua haujlwm ntev.
Cov Kauj Ruam Ua Haujlwm Yooj Yim
Siv lub sensor no yooj yim heev. Nov yog ib txoj haujlwm ib txwm muaj:
Kev teeb tsa
- Mount lub sensor ntsug lossis kab rov tav rau hauv lub flow cell, qhib channel, lossis ncaj qha rau hauv lub tank siv lub holder tsim nyog.
- Txuas lub RS-485 (Modbus) interface rau koj lub data logger, PLC, lossis SCADA system. Qhov ntev ntawm cable yog 10 meters.
Ua kom muaj zog
- Muab DC 12V (± 5%, tam sim no <50 mA tsis muaj wiper). Lub sensor yog IP68 rated, tsim rau kev ua haujlwm hauv qab dej txog li 1 bar siab.
Kev kho kom raug
- Rau kev teeb tsa thawj zaug, ua ib lossis ob-taw tes rau tus neeg siv calibration siv cov tshuaj txheem (piv txwv li, KHP rau COD/BOD/TOC). Kev calibration xoom nrog dej deionized kuj tseem pom zoo.
- Lub Hoobkas calibration twb khaws cia lawm; tus neeg siv calibration fine-tunes rau cov dej matrices tshwj xeeb.
Pib Ntsuas
- Lub sensor tso tawm cov nqi tiag tiag rau COD, BOD, TOC, thiab turbidity los ntawm Modbus RTU.
- Lub txhuam ntxuav nws tus kheej (lub ntaub so) tuaj yeem ua haujlwm manually lossis cia li ntxuav cov qhov rai optical, ua kom ntev lub sijhawm txij nkawm.
Kev Sau Cov Ntaub Ntawv & Kev Tswj Xyuas
- Muab cov ntaub ntawv digital tso rau hauv koj lub tshuab automation kom ua rau muaj kev ceeb toom, kho qhov nrawm ntawm kev ua pa, lossis ua kom zoo dua qhov kev siv tshuaj hauv cov txheej txheem kho dej khib nyiab.
Cov Lus Qhia Tseem Ceeb ntawm Ib Saib Ib Muag
| Cov Qauv | Ntau yam | Kev raug | Kev daws teeb meem |
|---|---|---|---|
| COD | 0.1 – 1500 mg/L (KHP) | <5% | 0.01 mg/L |
| BOD | 0.1 – 900 mg/L (KHP) | <5% | 0.01 mg/L |
| TOC | 0.1 – 750 mg/L (KHP) | <5% | 0.1 mg/L |
| Qhov tsis huv | 0.1 – 4000 NTU | <3% lossis 0.2 NTU | 0.1 NTU |
| Kub | +5 – 45 °C | — | — |
Vim li cas ho xaiv qhov Sensor no?
- ✅Tsis muaj reagents, tsis muaj pov tseg, tsis muaj kuab paug
- ✅ Cov zis COD, BOD, TOC, thiab turbidity tib lub sijhawm
- ✅ Kev them nyiaj rau qhov turbidity kom raug rau cov qauv kuaj tiag tiag
- ✅ Txhuam ntxuav nws tus kheej rau kev saib xyuas yooj yim
- ✅ Digital RS‑485 Modbus rau kev sib koom ua ke yooj yim
- ✅IP68, tsim nyog rau cov xwm txheej hauv thaj chaw hnyav

Txawm koj tab tom saib xyuas cov dej ntws, cov dej khib nyiab, lossis cov dej ua haujlwm hauv ib lub nroog lossis lub Hoobkas lag luam, lub Digital RS485 Output COD sensor muab kev hloov pauv sai, huv si, thiab pheej yig dua li cov COD analyzers ib txwm muaj. Nws muab cov ntaub ntawv tas mus li, lub sijhawm tiag tiag uas pab koj nrhiav pom cov xwm txheej ua qias tuaj thaum ntxov, ua kom cov txheej txheem kho kom zoo dua, thiab txo cov nqi ua haujlwm - tag nrho thaum tshem tawm cov tshuaj lom neeg txaus ntshai.
