Muongorori weCOD wepamhepo
Nheyo yeKuona
Wedzera huwandu hunozivikanwa hwe potassium dichromate solution mumvura, uye shandisa munyu wesirivha sechinhu chinobatsira uye mercury sulfate sechinhu chinovhara ganda munzvimbo ine acid yakasimba. Mushure mekuita kwekugaya kwakasimba uye kumanikidzwa kwakanyanya, tarisa kunyudzwa kwechigadzirwa pahurefu hwakati. Sekureva kwemutemo waLambert Beer, pane hukama hwakatwasuka pakati pehuwandu hwe oxygen demand mumvura uye kunyudzwa, wobva waona huwandu hwe oxygen demand mumvura. Cherechedza: Kune zvakaoma kuoxida zvinhu zvakaita se aromatic hydrocarbons ne pyridine mumvura, uye nguva yekugaya inogona kuwedzerwa zvakakodzera.

Hunhu
1. Iyo analyzer ine saizi ye miniaturization, iyo iri nyore kugadzirisa zuva nezuva;
2. Kuyera kwemagetsi nemagetsi zvine hungwaru uye tekinoroji yekuona zvinhu zvinoshandiswa kugadzirisa nzvimbo dzakasiyana-siyana dzemvura dzakaoma;
3. Zvikamu zvitatu (0-100mg/L), (0-200mg/L) uye (0-1000mg/L) zvinogutsa zvinodiwa zvakanyanya zvekutarisa hunhu hwemvura. Zvikamu izvi zvinogonawo kuwedzerwa zvichienderana nemamiriro chaiwo;
4. Nzira dzekuyera dzakagadziriswa, dzinogara dzichishandiswa, dzinochengetedza uye dzimwe nzira dzekuyera dzinozadzisa zvinodiwa zvekuyera kakawanda;
5. Inoderedza mari yekushandisa nekugadzirisa nekushandisa ma reagents mashoma;
6. 4-20mA,RS232/RS485 nedzimwe nzira dzekutaurirana dzinozadzisa zvinodiwa pakutaurirana;
Mashandisirwo
Iyi analyzer inonyanya kushandiswa pakutarisa okisijeni yemakemikari panguva chaiyo
kudiwa (CODc r) co
