Umwuka wa ogisijeni ukenewe (COD) bivuga ubwinshi bwa ogisijeni ikoreshwa na okiside iyo ihumanya ibintu bigabanya umubiri mu ngero z’amazi hamwe na okiside ikomeye mu bihe bimwe na bimwe. COD kandi ni igipimo cyingenzi kigaragaza urugero rw’umwanda w’amazi ukoresheje ibintu ngengabuzima na organique bigabanya ibintu.
Isesengura rishobora gukora mu buryo bwikora kandi ubudahwema igihe kirekire utitabye ukurikije igenamiterere ryurubuga. Ikoreshwa cyane mumasoko y’umwanda asohora amazi y’amazi, gutunganya amazi y’inganda, amazi y’inganda zitunganya imyanda y’inganda, amazi y’imyanda itunganya imyanda n’ibindi bihe. Ukurikije imiterere yikizamini cyibibanza, sisitemu ijyanye no kwitegura irashobora gutoranywa kugirango inzira yikizamini yizewe, ibisubizo byikizamini ni ukuri, kandi bihuze neza ibikenewe mubihe bitandukanye.
2. Ihame ry'ibicuruzwa:
Ingero zamazi, potasiyumu dichromate yumuti wigifu, igisubizo cya sulfate ya silver (sulfate ya silver nka catalizator irashobora kongerwamo imbaraga kugirango oxydeize alifatique igizwe neza) hamwe nuruvange rwa acide sulfurike yashushe kugeza 175 ℃. Ibara ryibintu kama muri dichromate ion okiside yumuti bizahinduka. Umusesenguzi amenya ihinduka ryamabara kandi ahindura impinduka mubiciro bya COD hanyuma asohora agaciro. Ingano ya ion ya dichromate yakoreshejwe ihwanye nubunini bwibintu byangiza umubiri, aribyo COD.
2. Ibipimo bya tekiniki:
| Oya. | Izina | Ibisobanuro bya tekiniki |
| 1 | Urwego rwo gusaba | Birakwiriye kumazi mabi hamwe na COD murwego rwa 10 ~ 5.000mg / L hamwe na chloride yibanze munsi ya 2.5g / L Cl-. Ukurikije ibyifuzo byabakiriya, birashobora kwaguka kumazi yanduye hamwe na chloride yibanze munsi ya 20g / L Cl-. |
| 2 | Uburyo bwo Kwipimisha | Potasiyumu igogora igogorwa ryubushyuhe bwinshi, kugena amabara |

| 9 | Ikirangantego | ± 10% |
| 10 | Inzira yo gupima | Nibura iminota 20. Ukurikije icyitegererezo cyamazi nyirizina, igihe cyo gusya gishobora gushyirwaho kuva muminota 5 kugeza kuri 120. |
| 11 | Igihe cyo gutoranya | Intera yigihe (irashobora guhinduka), isaha yibanze cyangwa imbarutso yo gupima irashobora gushirwaho. |
| 12 | Calibration ukwezi | Ihinduramiterere ryikora (iminsi 1-99 irashobora guhinduka), ukurikije urugero rwamazi nyayo, kalibrasi yintoki irashobora gushirwaho. |
| 13 | Inzira yo gufata neza | Intera yo gufata neza irenze ukwezi, iminota 30 buri mwanya. |
| 14 | Imikorere-imashini | Gukoraho ecran yerekana no kwinjiza amabwiriza. |
| 15 | Kwirinda wenyine | Imiterere yakazi ni kwisuzumisha, bidasanzwe cyangwa kunanirwa imbaraga ntibizabura amakuru. Mu buryo bwikora ikuraho reaction zisigaye hanyuma igakomeza imirimo nyuma yo gusubiramo bidasanzwe cyangwa kunanirwa kwamashanyarazi. |
| 16 | Kubika amakuru | Ntabwo ari munsi yigice cyumwaka kubika amakuru |
| 17 | Iyinjiza | Hindura ingano |
| 18 | Imigaragarire | Babiri RS485 isohoka muburyo bwa digitale, Imwe 4-20mA isohoka |
| 19 | Imiterere y'akazi | Gukorera mu nzu; ubushyuhe 5-28 ℃; ugereranije n'ubushuhe≤90% (nta kondegene, nta kime) |
| 20 | Gukoresha Amashanyarazi | AC230 ± 10% V, 50 ~ 60Hz, 5A |
