KDN-04D蛋白質(zhì)測定儀是一款基于凱氏定氮法原理設(shè)計(jì)的檢測設(shè)備，廣泛應(yīng)用于食品加工、農(nóng)產(chǎn)品檢驗(yàn)、飼料生產(chǎn)、科研實(shí)驗(yàn)等領(lǐng)域。該儀器由消化器和蒸餾器兩大部分組成，消化部分采用井式電加熱裝置，使樣品在消化管內(nèi)能夠快速且高效地完成消化過程。其測定范圍為含氮量0.05%-90%，精度高，相對差≤2%，平行差≤0.2%，測定時(shí)間短，消化約45分鐘，蒸餾約6分鐘。此外，該儀器配備7英寸彩色觸摸屏，操作界面直觀，數(shù)據(jù)管理系統(tǒng)完善，用戶可輕松完成參數(shù)設(shè)置、流程監(jiān)控及結(jié)果查詢。

The KDN-04D Protein Determination Instrument is a detection device designed based on the Kjeldahl nitrogen determination method. It is widely used in food processing, agricultural product inspection, feed production, scientific research experiments, and other fields. The instrument consists of two main parts: a digester and a distiller. The digester uses a well-type electric heating device, enabling the samples in the digestion tube to be digested quickly and efficiently. With a nitrogen content measurement range of 0.05%-90%, the instrument boasts high precision, with a relative difference of ≤2% and a parallel difference of ≤0.2%. The digestion process takes about 45 minutes, and distillation takes about 6 minutes. Moreover, the instrument is equipped with a 7-inch color touch screen. The operation interface is intuitive, and the data management system is comprehensive, allowing users to easily complete parameter settings, process monitoring, and result queries.
