SKD-5800 fully automatic Kjeldahl nitrogen analyzer Introduction: The fully automatic Kjeldahl nitrogen analyzer (protein analyzer) is a set of automatic intelligent detection instruments designed based on the classic Kjeldahl nitrogen determination principle. It is widely used to detect the overall content of ammonia nitrogen and protein nitrogen in grain, oil, food, dairy products, beverages, feed, soil, fertilizers, medicine, sediment, and chemical products. It is an important physical and chemical analysis instrument for product quality testing. The fully automatic Kjeldahl nitrogen analyzer adopts a brand new long-life design, intelligent microcomputer control, LCD color touch screen operation, and automatically completes a series of standardized processes such as acid addition, alkali addition, diluent addition, distillation, titration, cleaning, storage, printing, etc. It is equipped with a 40 bit automatic sampling system, realizing unmanned and fully automatic analysis. It is equipped with a refrigeration system that does not require the consumption of tap water. The titration uses international standard color method judgment (color sensor), which is easy to operate, accurate data, and stable performance. Features: 1. 40 position automatic sampler - ① The sample digestion stand can be directly placed inside the sampler, which is convenient and fast; ② Automatic detection of the front and rear two supports in place, no frame not working; ③ Automatic detection of digestive tract in place, no operation without tubes; ③ Sample door closed detection, does not close the door and does not work; ④ One click to complete automatic analysis of 1-40 samples 2. 10 inch color touch screen, user-friendly and easy to learn human-machine dialogue operation 3. The fully automatic Kjeldahl nitrogen analyzer without the need for tap water is equipped with an efficient cold water circulation system controlled by the nitrogen analyzer host, which is energy-saving, environmentally friendly, and has good stability 4. Third level user management meets relevant certification requirements, and the operation traceability query system 5. The simultaneous distillation and titration mode can save analysis time and reduce ineffective distillation electricity consumption 6. The imported linear motor and injection needle tube form a "plunger titration pump", with high control accuracy and stability 7. The titration cup is clearly packaged, making it convenient for users to observe the titration process and clean the titration cup 8. Automatic cleaning of alkali pipelines after shutdown to prevent pipeline blockage and ensure liquid supply accuracy 9. Operation methods, reagent preparation, precautions, and maintenance screen queries are convenient for users to use in their daily lives 10. PID regulated steam system can provide stable steam flow rate to ensure effective sample separation 11. Cooling water flow monitoring can prevent insufficient cooling water flow from causing sample loss and affecting analysis results 12. Multi functional interface can connect refrigeration system and reagent tank liquid level sensor 13. 99 User Defined Programs (Recipes) Management System 14. 16M data storage capacity can store 1 million sample data for users to refer to 15. 5.7CM automatic paper cutting thermal printer 16. Protection system: leakage protection, digestive tube vacancy protection, door alarm system, steam system water shortage alarm, steam boiler overtemperature alarm, steam overpressure alarm, sample overtemperature alarm, and alkali adding mode can reduce the strong reaction during the alkali adding process and prevent the occurrence of tube explosion phenomenon 17. Automatic discharge of digestive waste liquid to reduce labor intensity of workers Technical parameters: Analysis range: 0.1-240 mg N Precision (RSD): ≤ 0.5% Recovery rate: ≥ 99.5% (± 0.5%) Titration accuracy: 0.75 μ L/step Sample analysis time: 4-6 minutes/(cooling water temperature 18 ℃) Titration mode: standard/drip while steaming Touch screen: 10 inch color LCD touch screen Automatic sampling system: 40 bits Data storage capacity: 100000 sets of data Printer: 5.7CM thermal automatic paper cutting printer Communication interface: 232/network/cooling water/reagent level Delay analysis: reaction time 0-7200S Steam flow regulation: 40% -100% Alkali addition mode: 0-99 seconds Automatic shutdown time: 60 minutes Working voltage: AC220V/50Hz Heating power: 2000W
