Kjeldahl nitrogen analyzer is an instrument that calculates the protein content by measuring the nitrogen content in the sample based on the principle that the nitrogen content in the protein is constant. The automatic Kjeldahl nitrogen analyzer realizes the automation of distillation, titration and other steps, reduces manual operation, reduces human error and risk factor.

In the process of food analysis, since the nitrogen content of protein is relatively constant, the protein content can be calculated from its nitrogen content, so the Kjeldahl method is also a classic protein determination method. Auto Kjeldahl apparatus can be widely used in food processing, feed production, animal husbandry, soil and fertilizer, environmental monitoring, medicine, scientific research, teaching, quality supervision and other fields for constant and semi-trace sample analysis.

In the field of agriculture, the automatic Kjeldahl nitrogen analyzer can also be used as a soil testing instrument, which can assist in soil census, soil research, soil improvement and other projects.

In addition, there are automatic Kjeldahl analyzer and digital display digester. The full automatic nitrogen analyzer can automatically complete the titration operation, automatic waste discharge, automatic cleaning of the titration cup, etc. It is an ideal testing equipment in modern laboratories.
