1.Pfupiso yeChigadzirwa:
Kudiwa kweokisijeni yemakemikari (COD) zvinoreva kuwanda kweokisijeni inodyiwa nemakemikari kana ichiisa okisijeni muzvinhu zvinoderedza okisijeni mumienzaniso yemvura ine maokisijeni akasimba pasi pemamwe mamiriro ezvinhu. COD chiratidzo chakakosha chinoratidza huwandu hwekusvibiswa kwemvura nezvinhu zvinoderedza okisijeni.
Chinoongorora chinogona kushanda otomatiki uye nguva dzose kwenguva yakareba pasina kupindira zvichienderana nemamiriro enzvimbo yacho. Chinoshandiswa zvakanyanya mumvura inobuda mumaindasitiri, mvura inobuda mumaindasitiri, mvura inobuda mumaindasitiri, mvura inobuda mumaindasitiri nezvimwewo zviitiko. Zvichienderana nekuoma kwemamiriro ekuyedza nzvimbo, sisitimu yekugadzirira inogona kusarudzwa kuti ive nechokwadi chekuti maitiro ekuyedza akavimbika, mhedzisiro yebvunzo yakarurama, uye inosangana zvizere nezvinodiwa zvezviitiko zvakasiyana.
2.Nheyo yeChigadzirwa:
Mienzaniso yemvura, potassium dichromate digestion solution, silver sulfate solution (silver sulfate se catalyst inogona kuwedzerwa kuti ioxide linear aliphatic compounds zvinobudirira) uye concentrated sulfuric acid musanganiswa inopiswa kusvika 175℃. Ruvara rwe organic compounds mu dichromate ion oxidation solution ruchachinja. Analyzer inoona shanduko yeruvara uye inoshandura shanduko kuita COD value yobva yaburitsa kukosha. Huwandu hwe dichromate ion inodyiwa hwakaenzana nehuwandu hwe organic matter inooxidable, kureva COD.
3.Magadzirirwo ehunyanzvi:
| Aihwa. | Zita | Magadzirirwo ehunyanzvi |
| 1 | Mhando dzeKushandiswa | Yakakodzera mvura yakasviba ine COD iri pakati pe10~5,000mg/L uye chloride iri pasi pe2.5g/L Cl-. Zvichienderana nezvinodiwa nevatengi, inogona kuwedzerwa kusvika kumvura yakasviba ine chloride iri pasi pe20g/L Cl-. |

| 10 | Kutenderera kwekuyera | Maminetsi makumi maviri. Zvichienderana nemuenzaniso chaiwo wemvura, nguva yekugaya inogona kusarudzwa kubva pamaminitsi mashanu kusvika zana nemakumi maviri. |
| 11 | Nguva yekutora sampuli | Nguva inogadziriswa (inogadziriswa), integral hour kana trigger measurement mode inogona kuiswa. |
| 12 | Kuenzanisa kutenderera | Kuongororwa otomatiki (kunogadziriswa kwemazuva 1-99), zvichienderana nemasampuli emvura chaiwo, kuongororwa nemaoko kunogona kugadziriswa. |
| 13 | Kugadzirisa nguva | Nguva yekuchengeta inopfuura mwedzi mumwe chete, ingangoita maminetsi makumi matatu nguva imwe neimwe. |
| 14 | Kushanda kwemuchina wemunhu | Kuratidzwa kwechidzitiro chekubata uye kuiswa kwemirairo. |
| 15 | Kuzvidzivirira pakuzviongorora | Kushanda kunozviongorora, kana kuti kukundikana kwemagetsi hakuzorasikirwi nedata. Kunobvisa otomatiki ma reactants akasara uye kunoenderera mberi nekushanda mushure mekugadziriswazve kusina kujairika kana kukundikana kwemagetsi. |
| 16 | Kuchengetedza data | Kuchengetedza data kweinenge hafu yegore |
| 17 | Chinongedzo chekupinda | Switch huwandu |
| 18 | Chinobuda chinobuda | Kubuda kwedhijitari kweRS485 kaviri, Kubuda kweanalog imwe chete ye4-20mA |
