HGK-51N Kjeldahl nitrogen analyzer Introduction: The HGK-51N Kjeldahl nitrogen analyzer is widely used to detect the overall content of ammonia nitrogen and protein nitrogen in grain, oil, food, dairy products, beverages, feed, soil, fertilizers, drugs, sediments, and chemical products. It is an important physical and chemical analysis instrument for product quality testing. Features: 1. Using a 7-inch touch color screen single chip computer control, automatically adding acid, distillation, setting storage data, etc., real-time display and tracking of various status operations; 2. The overall use of ABS engineering plastic molds for the shell is injection molded, which is resistant to strong acids and alkalis, and has insulation properties; 3. The connections of various pipelines inside the instrument are made of specially made rubber hoses that are resistant to high temperature, strong acid and alkali, which improves the performance and service life of the instrument and does not require replacement for 3 years; 4. The use of a pressure free metering pump for adding boric acid/alkali/diluent/distilled water resulted in consistent addition of each liquid; 5. The selection of anti-corrosion, heat-resistant, and pressure resistant materials in the design, material selection, production process, and instrument casing; High performance solenoid valves, anti-corrosion pump seals, and other components ensure the effective lifespan of the instrument; 6. The distillation cup adopts Hercules * technology to prevent dry burning and eliminate safety hazards; 7. Storage quantity: Programmable to store 1000 different methods of adding acid, diluent, and distillation time for various programs; 8. Real time tracking and monitoring of the experimental conditions in various experimental environments, with the function of voice broadcasting; 9. Implement real-time paperless operation instructions, remote upgrades, and troubleshooting; 10. Energy saving distillation method for cooling water. When distillation starts, the cooling water automatically turns on, and when leisure time, the cooling water automatically turns off. Technical parameters: Measurement range: 0.06-240mgN; CEC (0.07cmol/KG-14mol/KG) Measurable sample size: solid ＜ 5g liquid ＜ 15ml; (CEC (0-30 grams) (Excessive or insufficient samples can affect pre-treatment and distillation) Using a matching distillation tube of 750ml; 300ml Automatic addition of boric acid (measured in ml) and multi-level adjustable exchange time and distillation power (soil cation exchange capacity); Recovery rate:>99.5%; Repeatability: RSD ≤ 0.5%; Distillation speed: 3-9 minutes per sample; Distillation time: can be set according to the actual sample; Distillation power: 0-1500W adjustable; Delay time: 0-3600 seconds (for easy detection of fertilizers); Distillation capacity: 0-30ml/min adjustable; Cooling water: water pressure>0.15 Mpa; Cooling water consumption:<2L/min (water temperature ≤ 20 degrees); Rated voltage: AC220 ± 10%;
