KDN-20K fully automatic nitrogen analyzer Introduction: KDN-20K full-automatic nitrogen determination instrument, based on the classic Kjeldahl method, adopts rigorous logic algorithm, combined with humanized operation interface and intelligent microcomputer system control, can quickly, conveniently and accurately detect the nitrogen element and protein content in the sample, and the whole process does not require personnel to be on duty. Both high protein and low protein samples with unknown content can be tested. In addition, the manual mode of the instrument can operate each step separately, greatly improving the flexibility of operation and the applicability of the instrument. The unique one click blank detection and automatic input of blank values, as well as the one click empty steaming cleaning instrument, greatly facilitates users' daily testing and instrument maintenance work. The operation, setup, and testing database of the instrument are managed by three-level permissions. The detected data can be directly printed using the instrument's built-in printer, or exported in bulk to a USB flash drive for editing and summary statistics. In terms of safety, 20K has also made various considerations and designs to ensure the safe operation of personnel and instruments, perfectly balancing safety while automating high efficiency. In terms of application, the 20K has four built-in calculation formulas. In addition to meeting the requirements of national standard formulas such as GB 5009.5-2016, GB/T 6432-2018, and GB/T 22923-2008, it also supports the formula for water quality testing in GB 11891-89, which can adapt to more industries and national standard requirements, and is more user-friendly. characteristic: 1. Third level user permission management 2. Detection data can be exported via USB 3. The titration system adopts dynamic titration technology, which titrates while distilling, and can automatically determine unknown samples and adjust the titration speed, 4. The waste liquid from the digestion tube and receiving bottle is automatically emptied and cleaned 5. The protective door automatically opens and closes to prevent splashing caused by digestive tube rupture during distillation 6. Titration residual monitoring, insufficient alarm reminder added 7. Evaporation furnace: Real time water level, temperature, and pressure monitoring, anti dry burning device, abnormal alarm 8. Real time monitoring of condensate flow, alarm for insufficient flow 9.
