Kjeldahl nitrogen analyzer, also known as protein analyzer, crude protein analyzer, is used for nitrogen or protein determination in food processing, feed production, tobacco, animal husbandry, soil and fertilizer, environmental monitoring, medicine, agriculture, scientific research, teaching, quality supervision, etc., as a basic instrument for determining the nitrogen content of a sample.

The Kjeldahl analyzer can quickly determine the nitrogen content of the sample, and with corresponding measures, the nitrogen content can be effectively controlled. it can also determine the nitrogen content in soil, so as to know whether it is lacking nitrogen content or whether it exceeds the standard. In this way, it helps to improve the utilization rate of nitrogen fertilizer, decrease the pollution of nitrogen fertilizer to the environment, and reduce the expenditure on nitrogen fertilize. The Kjeldahl apparatus can determine the nitrogen content in food to prevent the reaction of excessive nitrogen content, and can be used to monitor food safety to prevent bad food from entering the market.

The 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. Automatic Kjeldahl nitrogen analyzer and full automatic Kjeldahl nitrogen analyzer have stable performance, fast measurement speed and high accuracy of measurement results, and play a very important role in all walks of life.
