Kufunika kwa okosijeni wa Chemical (COD) kumatanthauza kuchuluka kwa okosijeni womwe umagwiritsidwa ntchito ndi okosijeni pamene akutulutsa zinthu zochepetsera organic ndi organic mu zitsanzo za madzi okhala ndi ma okosijeni amphamvu nthawi zina. COD ndiwonso mlozera wofunikira wowonetsa kuchuluka kwa kuipitsidwa kwa madzi ndi zinthu zochepetsera organic ndi organic.
Analyzer imatha kugwira ntchito yokha komanso mosalekeza kwa nthawi yayitali osapezekapo malinga ndi makonda atsamba. Amagwiritsidwa ntchito kwambiri m'mafakitale owononga gwero lamadzi otayira, madzi otayira m'mafakitale, m'mafakitale ochapira zimbudzi, madzi onyansa amadzimadzi, madzi otayira am'matauni ndi zina. Malinga ndi zovuta za mayeso a malo, njira yofananira yoyeserera ikhoza kusankhidwa kuti zitsimikizire kuti mayesowo ndi odalirika, zotsatira zoyeserera ndi zolondola, komanso zimakwaniritsa zosowa zanthawi zosiyanasiyana.
2. Mfundo Zogulitsa:
Zitsanzo za madzi, potassium dichromate digestion solution, silver sulfate solution (silver sulfate as catalyst can be add to oxidize linear aliphatic compounds) ndi kusakaniza kwa sulfuric acid kutenthedwa kufika 175 ℃. Mtundu wa organic compounds mu dichromate ion oxidation solution udzasintha. The analyzer detects mtundu kusintha ndi kusintha kusintha mu COD mtengo ndiye kutulutsa value.The kuchuluka kwa dichromate ion kudya n'chofanana ndi kuchuluka kwa oxidizable organic matter, ndicho COD.
2. Zofunikira zaukadaulo:
| Ayi. | Dzina | Mfundo Zaukadaulo |
| 1 | Ntchito Range | Oyenera madzi oipa okhala ndi COD mu 10 ~ 5,000mg/L ndi chloride concentration yochepera 2.5g/L Cl-. Malinga ndi zomwe makasitomala amafuna, zitha kuwonjezeredwa kumadzi onyansa okhala ndi chloride zosakwana 20g/L Cl-. |
| 2 | Njira Zoyesera | Potaziyamu dichromate chimbudzi pa kutentha kwambiri, colorimetric kutsimikiza |
| 3 | Muyezo osiyanasiyana | 10-5,000mg/L |
| 4 | Kuchepetsa malire a Kuzindikira | 3 |
| 5 | Kusamvana | 0.1 |
| 6 | Kulondola | ± 10% kapena ± 8mg/L (Tengani mtengo wokulirapo) |
| 7 | Kubwerezabwereza | 10% kapena 6mg/L (Tengani mtengo wokulirapo) |
| 8 | Zero Drift | ± 5mg/L |
| 9 | Pitani ku Drift | ±10% |
| 10 | Kuyeza kuzungulira | Osachepera mphindi 20. Malinga ndi chitsanzo chenicheni cha madzi, nthawi ya chimbudzi ikhoza kukhazikitsidwa kuchokera ku 5 mpaka 120 mphindi. |
| 11 | Nthawi yochitira zitsanzo | Nthawi yanthawi (yosinthika), ola lofunikira kapena muyeso woyambitsa akhoza kukhazikitsidwa. |
| 12 | Kuwongolera kuzungulira | Ma calibration okha (masiku 1-99 osinthika), malinga ndi zitsanzo zenizeni zamadzi, kuwongolera pamanja kumatha kukhazikitsidwa. |
| 13 | Kukonzekera kozungulira | Nthawi yokonza ndi yopitilira mwezi umodzi, pafupifupi mphindi 30 nthawi iliyonse. |
| 14 | Kugwiritsa ntchito makina a anthu | Chiwonetsero cha touch screen ndi kulowa kwa malangizo. |
| 15 | Chitetezo chodzifufuza | Kugwira ntchito ndikudzifufuza, kusakhazikika kapena kulephera kwamphamvu sikutaya deta. Zimachotsa zokha zotsalira zotsalira ndikuyambiranso ntchito pambuyo pokonzanso modabwitsa kapena kulephera kwamagetsi. |
| 16 | Kusungirako deta | Osachepera theka la chaka yosungirako deta |
| 17 | Lowetsani mawonekedwe | Sinthani kuchuluka |
| 18 | Linanena bungwe mawonekedwe | Kutulutsa kwa digito kwa RS485, Kutulutsa kwa analogi kumodzi kwa 4-20mA |
| 19 | Zogwirira Ntchito | Kugwira ntchito m'nyumba; kutentha 5-28 ℃; chinyezi wachibale ≤90% (palibe condensation, palibe mame) |
| 20 | Kugwiritsa Ntchito Mphamvu | AC230±10%V, 50~60Hz, 5A |
| 21 | Makulidwe | 355×400×600(mm) |
