Introduction: KDN-19K automatic nitrogen analyzer, based on the classic Kjeldahl method, is safe, fast, accurate, low consumption and user-friendly. A variety of operation modes, automatic mode: distillation titration is fully automatic, no need for personnel on duty, and protein analysis results are automatically calculated; manual mode: adding alkali, adding acid, adding distilled water, and distillation can be controlled individually or at the same time; automatic titration, Manual titration can also be mixed. The difference is that the user-approved color can be arbitrarily set as the end point; on the basis of the conventional color judgment sensor, the company's original color filtering technology and the adjustable jitter judgment function are used to make the color method end point judgment accurate. Correct, the color difference value and curve are displayed directly, allowing users to see the judgment process of the instrument. In addition, a flexible open titration debugging system is built-in, and users can easily set the titration parameters, fully demonstrating the system logic capability of 19K. The design and development of the 19K incorporates more than 30 years of manufacturing experience in fiber inspection and the majority of users' desire to improve the automatic nitrogen analyzer. It is suitable for users who require high accuracy of test results. Features 1. Adopt international standard Kjeldahl nitrogen determination method: concentrated sulfuric acid digestion, alkaline environment steam distillation, boric acid absorption, indicator titration endpoint color determination method; 2. The continuous titration method can be used for unlimited titration without pumping reagents back and forth; 3. The user-approved color can be arbitrarily set as the end point; 4. The three-stage titration speed is automatically involved to ensure fast and accurate; 5. Setting pre-titration for samples with known concentration can greatly improve the titration speed; 6. Automatic waste cleaning; 7. Manual and automatic integration, a variety of manual functions; 8. Special reagent barrel with low liquid level alarm function; 9. Anti-emergency: the test can be continued after the power is cut off, without affecting the test effect of the current sample; avoid the sample being scrapped due to unexpected events; 10. The anti-splash pipe material is made of strong acid and alkali resistant plastic, with good sealing performance, stronger alkali resistance than glass, and long service life; 11. ABS shell, beautiful, anti-corrosion and durable; 12. The evaporation furnace has a pressure relief valve, which increases the safety of the instrument; Technical parameter: Measurement range: 0.1～240.0mg nitrogen; Sample weight: The empirical value is 0.3~8.0g for solid and 2.0~30.0ml for liquid; Accuracy: relative difference of 0.3%; Repeatability: Parallelism ≤0.2%; Recovery rate: ≥99.5%; Measurement speed: 3～8min/sample; Condensation water consumption: 1.4L/min; Evaporation furnace overvoltage protection: support; Data storage: 1000 sets Operation mode: Distillation and titration are both manual and automatic dual modes; Display mode: 7-inch LCD ultra-fine color screen; Control method: touch; Titration volume: 50µl~unlimited; Titration accuracy: 0.1μl/step Titration speed: 60~120 drops/min adjustable; End color: can be set freely; Pre-titration: 0~99ml can be set; Calculation method: automatically calculate the final result; Power: 1200W; Power supply: 220V±10%, 50～60HZ; Size: 460×410×730(mm); Weight: 32kg;
