Features: 1. Kjeldahl nitrogen determination method using international standards: concentrated sulfuric acid digestion, alkaline environmental steam distillation, boric acid absorption, indicator titration end color determination method 2. Working mode: manual and automatic integration, can be switched at any time 3. Automatic mode: add water, add alkali, add boric acid, distillation, one-click to complete. (Without titration) 4. Manual mode: each step is controlled separately, either separately or simultaneously 5. Automatic quantitative filling of alkaline solution and boric acid receiving solution 6. Automatically stop and alarm when the distillation is over 7. Emergency stop function to prevent unexpected situations 8. Display mode: 7-inch LCD superfine color widescreen display 9. Control panel: touch 10. Operation monitoring and fault indication of 8 major components such as water and alkali pumps and valves 11. Dedicated reagent barrel with liquid level indicator 12. Anti-emergency events: can continue to test after power off, does not affect the test effect of the current sample, to avoid emergencies leading to sample scrap 13. Splash-proof tube material: high-performance strong acid-base plastic mold is used for one-time molding, with good sealing performance, stronger alkali resistance than glass, and long service life 14. The receiving bottle automatically falls and rinses the receiving tube, which is more in line with the national standard operation requirements to ensure the test results are accurate 15.ABS shell, beautiful and durable Technical Parameters: Measuring range: 0.1～240.0mg nitrogen; Sample weight: The empirical value is solid 0.3～8.0g, liquid 2.0～30.0ml; Accuracy: relative difference 0.3%; Repeatability: parallel difference ≤0.2%; Recovery rate: ≥99.5%; Measurement speed: 3～8min/sample; Distillation time: arbitrarily set from 0 to 9999 seconds; Built-in 4 micropumps to independently draw reagents; The splash-proof tube is formed at one time by a high-performance strong acid-base plastic mold; Condensation water consumption: 1.4L/min; Operation mode: automatic/manual dual mode switch at any time; Display mode: 7-inch LCD ultra-fine color screen; Control mode: touch type; Power: 1200W; Power supply: 220V±10%, 50～60HZ; Size: 420×410×760 (mm); Weight: 30kg;
