Introduction: Potentiometric automatic Kjeldahl nitrogen analyzer adopts intelligent program design, which not only has the functions of automatic acid addition, addition and subtraction, dilution and automatic cleaning in the whole process, but also realizes automatic distillation of the sample to convert ammonium salt into ammonia under alkaline conditions; Under the programmed conditions, the standard hydrochloric acid titration is automatically completed by the high-precision micro-metering pump, and the potential value measured by the high-precision PH electrode during the entire reaction process is used to automatically determine the end of the titration, so as to calculate the nitrogen content in the sample. The product has become an important physical and chemical analysis instrument for food companies, agriculture, forestry and fishery, such institutions, scientific research institutions, quality institutions and other departments. This product is suitable for food, beverage, medicine, agriculture, forestry and fishery, mining, chemical and other production enterprises, as well as universities, scientific research institutes, environmental monitoring, soil and fertilizer stations, agricultural machinery stations, quality supervision and inspection and other scientific research and testing units for food and dairy products , Natural rubber, latex, seeds, soil, plants, feed, ore, sludge and chemical sediments and other samples for the intelligent determination of protein content. Features: 1. BYNK6260 uses the potential blank method to determine the end point, abandoning the use of the traditional potential method The backward method of pH buffer for electrode slope calibration, the repeatability RSD is as high as less than five thousandths; 2. Potentiometric method does not need to use buffer to calibrate the electrode; 3. Built-in high-end 32-bit ARM processor, fast computing speed. Run U/COS-II real-time operating system, system System is stable and reliable; 4. Using 8.0-inch high-definition true color touch screen, the running interface is beautiful and generous, the operation introduction is clear, and it is more stylish Display interface such as status bar, potential, etc., can clearly watch the running status 5. It can display the change of the potential value of the reaction liquid in real time throughout the whole process; 6. Using imported high-precision micro-metering titration pump, titration accuracy is ultra-high; 7. Automatic completion of sample dilution, acid addition, alkali addition, distillation, titration, nitrogen tube emptying and cleaning, reaction cup Emptying and cleaning, automatic calibration, result calculation and output printing without human intervention. 8. Steam generator over-current and over-pressure protection, dry burning prevention, water flow detection, solution tank level detection, distillate temperature Detection etc. 9. It has a reagent tank liquid level detection sensor device, and has a liquid shortage alarm function; 10.
