DRK-K626 Automatic Kjeldahl Nitrogen Analyzer

Product description：

The Kjeldahl nitrogen analyzer is an instrument that calculates the protein content by measuring the nitrogen content in the sample based on the principle of constant nitrogen content in protein. Because the method of protein content measurement and calculation is called Kjeldahl method, it is called Kjeldahl nitrogen analyzer, also known as nitrogen analyzer, protein analyzer, and crude protein analyzer. The Kjeldahl nitrogen analyzer uses the Kjeldahl method to detect the content of ammonia, protein nitrogen, phenol, volatile fatty acid, cyanide, sulfur dioxide, ethanol, etc. in grains, food, feed, water, soil, silt, sediment and chemicals. It has a very good price-performance ratio, and only the titration process requires manual operation, which is very suitable for routine testing by laboratories and inspection institutions.It is widely used in the analysis of nitrogen or protein content of food, crops, seeds, soil, fertilizers and other samples. The DRK-K626 automatic Kjeldahl nitrogen determination instrument adopts the internationally accepted Kjeldahl nitrogen determination method to automatically distill nitrogen-containing samples. The fully intelligent software design allows the experimenter to easily complete the distillation of the sample within a few minutes. The complete safety system embodies the humanized wisdom of Derek. Automatic quantitative dosing of the required reagents, unattended in the whole process, intelligent detection of various states. The automatic distillation, automatic condensation, and automatic leaching system further improve the measurement accuracy. Drick equips the instrument with a multi-language version, which conforms to your language habits, and customizes the Chinese dialogue interface for Chinese users. The interface is friendly and the display information is rich, so that users can easily master the use of the instrument.
