A Dissolved Oxygen Meter chombo chinoshandiswa kuyera huwandu hweoxygen yakanyungudutswa mumvura kana zvimwe zvinwiwa. Inoita basa rakakosha mukutarisa kunaka kwemvura uye nekuona kwakaringana mwero weokisijeni mumatanho akasiyana. Inowanzo shandiswa mukurapwa kwemvura yetsvina, aquaculture, kutarisa kwezvakatipoteredza, uye ongororo yerabhoritari, inobatsira kuchengetedza biological chiyero uye kushanda zvakanaka. Uchishandisa tekinoroji yemagetsi kana yekuona tekinoroji, yakanyungudika okisijeni metres inopa chaiyo, yakagadzikana, uye chaiyo-nguva zviyero, zvichiita kuti ive yakakosha kune ese ari maviri munda uye maindasitiri mashandisirwo.
