The working principle of JK9870 auto Kjeldahl analyzer is based on the classical methods, it's namely the "color method" developed auto Kjeldahl analysis system. It is consistent with national and international standards and methods of Kjeldahl nitrogen. It's a high-performance instrument due to the concept of its design and application of new technologies, therefore, its comprehensive technical performance and very competitive price even much better than the similar products which the oversea competitors standing behind; thus, it becomes a very reasonable and logical choice to the Chinese local users as an outstanding import substitution.
