The KDN-2C Kjeldahl nitrogen determinator is a laboratory instrument designed based on the Kjeldahl nitrogen determination principle. It is widely used for the determination of protein content in grains, feeds, foods, dairy products, beverages, fertilizers, medicines, and other agricultural and sideline products. The instrument uses an electric heating tube for heating and can utilize tap water or distilled water as the water source. The distiller is equipped with a timing reception function. Its determination range is 0.05%-90% nitrogen content, with high precision, a relative difference of ≤2%, and a parallel difference of ≤0.2%. Harmful gases produced during the digestion process can be effectively prevented from escaping through the waste gas pipe and suction pump. The instrument has a size of 380×330×740mm and requires an AC220V/50Hz power supply. Manufacturers of this instrument include Shanghai Xinrui Instrument Co., Ltd and Shanghai Shuangxu Electronics Co., Ltd. These manufacturers have rich production experience and technical accumulation in the relevant field.
