Development of Android Operating System for Nitrogen Determinator’s Upper Computer

Project Background

The indirect reaction of crude protein and other substances content through the determination of nitrogen in food is an important link in the detection of food quality and quality. Kjeldberg nitrogen analyzer method is often used in the detection, but because this technology is still good and immature in China, it is easy to produce errors in manual operation, which has a certain impact on the experimental results. It is necessary to improve the speed and accuracy of measurement.

Scheme Introduction

By analyzing the principle of Kjeldahl nitrogen meter method and control system, unicrom and its customers designed a new type of automatic nitrogen meter to determine the content of material nitrogen. The system can quantitatively add alkali solution, quantitatively add boric acid absorption solution, automatically generate the required steam, hydrochloric acid solution, accurately determine the titration end point, automatic titration, clear display interface. Convenient parameter setting for manual operation, printing and computer management functions, automatic nitrogen analyser to achieve material nitrogen content determination with digital, intelligent and network advantages. It can be widely used in the detection of nitrogen content in seeds, dairy products, beverages, feed, soil and other agricultural and sideline products.
