長(zhǎng)沙巴躍COD消解儀

消解器執(zhí)行HJ828-2017水質(zhì)化學(xué)需氧量的測(cè)定，重鉻酸鹽法，分析方法規(guī)范地制定了水質(zhì)化學(xué)需氧量COD（cr）的測(cè)定步驟，嚴(yán)格地規(guī)定了方法的加熱消解時(shí)間、溶液酸度、氧化劑和催化劑的用量等條件指標(biāo)。顯而易見，水質(zhì)COD（cr）的測(cè)定是有嚴(yán)格的條件規(guī)定，違背了條件規(guī)定進(jìn)行操作，就會(huì)影響測(cè)定的準(zhǔn)確性。遵循了標(biāo)準(zhǔn)（ISO）和標(biāo)準(zhǔn)（HJ）的基本原則，保證了回流加熱微沸2小時(shí)的消解操作，試劑溶液的配制和加入量都和HJ法一致，確?？煽康姆治鼋Y(jié)果。

二、產(chǎn)品特點(diǎn)長(zhǎng)沙巴躍COD消解儀
系列COD消解器采用微機(jī)技術(shù)進(jìn)行定時(shí)控制加熱電爐，可對(duì)12個(gè)24#標(biāo)準(zhǔn)磨口的消解回流裝置同時(shí)進(jìn)行加熱。達(dá)到節(jié)能、減低電力負(fù)荷、提率的目的。

采用玻璃毛刺回流管代替球形回流管，并以風(fēng)冷技術(shù)取代自來水冷卻方式，既可以節(jié)水又能使儀器規(guī)范化，同時(shí)還提高了儀器使用的安全性。儀器的化學(xué)溶液配制、

操作和COD的計(jì)算完全遵照HJ828-2017，低于50mg/L的COD水樣可通過稀釋滴定劑和氧化劑來提高度，高于700mg/L的COD水樣，可以通過水樣的比例稀釋來完成測(cè)定。

三、技術(shù)特點(diǎn)
1、升降溫速度快。
2、消解瓶消解完畢后可直接滴定測(cè)量，方便搖勻。
3、加熱均勻、使用壽命長(zhǎng)。
4、可以設(shè)定消解時(shí)間，消解完畢后，儀器自動(dòng)停止加熱，可無人看管。
5、樣品消解完畢后，儀器風(fēng)機(jī)繼續(xù)工作，輔助樣品冷卻。
6、以風(fēng)冷取代水冷,節(jié)約用電、用水，提高了效率，增強(qiáng)了儀器的安全性。

I. product overview
QYC0D series COD disintegrators perform the determination of chemical oxygen demand (COD) in water quality from hj828-2017. Dichromate

method is used to formulate the determination steps of COD (cr) in water quality in a standardized way. The condition indexes of the method,

such as the heating and digestion time, the acidity of the solution, the amount of oxidant and catalyst, etc., are strictly specified. Obviously,

the determination of COD (cr) in water is subject to strict requirements. If the operation violates the requirements, the accuracy of the

determination will be affected. In accordance with the basic principles of international standard (ISO) and national standard (HJ),

the digestion operation of reflux heating micro boiling for 2 hours is guaranteed. The preparation and addition amount of reagent

solution are consistent with the HJ method, ensuring reliable and accurate analysis results.
Ii. Product features
QYC0D series COD disintegrator adopts microcomputer technology to control the heating electric furnace on time, which can be

used to heat 12 24# standard grinding mouth dissolving reflux devices at the same time. To save energy, reduce power load and

improve efficiency. Adopting glass burr reflux pipe instead of spherical reflux pipe and replacing tap water cooling with air cooling

technology can both save water and standardize the instrument, and at the same time improve the safety of the instrument.

The chemical solution preparation, operation and COD calculation of the instrument completely comply with hj828-2017.

COD water samples less than 50mg/L can be improved by diluting titrant and oxidant, while COD water samples

higher than 700mg/L can be determined by diluting the proportion of water samples.
