ʻO ka helu helu COD ma ka pūnaewele
Kumu ʻike
E hoʻohui i ka nui o ka solution potassium dichromate i ka laʻana wai, a e hoʻohana i ka paʻakai kālā ma ke ʻano he catalyst a me ka mercury sulfate ma ke ʻano he mea hoʻomakeke i loko o kahi mea ʻakika ikaika. Ma hope o ke kiʻekiʻe-mehana a me ke kiʻekiʻe-press digestion hopena, e ʻike i ka hoʻopaʻa ʻana o ka huahana ma kahi hawewe kikoʻī. E like me ke kānāwai Lambert Beer, aia ka laina laina ma waena o ka ʻike o ka oxygen koi i loko o ka wai a me ka absorbance, a laila e hoʻoholo i ka neʻe ʻana o ka koi oxygen kemika i ka wai.

1. He miniaturization ka mea anamanaʻo i ka nui, kahi kūpono no ka mālama ʻana i kēlā me kēia lā;
2. Hoʻohana ʻia ka mīkini kiʻi kiʻi kiʻekiʻe kiʻekiʻe a me ka ʻenehana ʻike e hoʻololi i nā kino wai paʻakikī;
3.ʻEkolu mau pae (0-100mg / L), (0-200mg / L) a me (0-1000mg / L) e hoʻokō i ka hapa nui o nā koi nānā wai. Hiki ke hoʻonui ʻia ka laulā e like me ke kūlana maoli;
4. Paʻa-point, periodic, mālama a me nā ʻano ana ʻē aʻe e hoʻokō i nā koi o ke ana pinepine;
5.E ho'ēmi i ka hana a me ka mālamaʻana i nā kumukūʻai ma ka hoʻohana haʻahaʻa o nā reagents;
6. 4-20mA, RS232/RS485andothercommunicationmethodssatisfy the communication requirements;
