Design Concept<\/h3>\n\n\n\n

Accurate and reliable measurement, sample protection, easy operation, two\u2011year maintenance\u2011free, three\u2011year free software upgrade. The principle of automatic Kjeldahl nitrogen analyzer is mature. However, it features highly corrosive reagents, simple structure, high\u2011temperature liquid and gas circuits. An accurate and reliable nitrogen analyzer shall be guaranteed by sound design concept, precise manufacturing process and qualified raw material selection.<\/p>\n\n\n\n

Product Features<\/h3>\n\n\n\n
    \n
  1. Safety: For laboratory operators<\/li>\n\n\n\n
  2. Door\u2011switch protection, digestion\u2011tube in\u2011place detection<\/li>\n\n\n\n
  3. Accuracy: All pipelines shall be well\u2011sealed, with precise liquid feeding, compensation and guarantee functions.<\/li>\n\n\n\n
  4. Fully\u2011sealed entire gas circuit. Independent liquid\u2011extraction pumps for acid, alkali and distilled\u2011water feeding. Distillation temperature compensation, distillate temperature detection & control, adjustable distillation power, manual alkali supplement and intermittent feeding.<\/li>\n\n\n\n
  5. Sample protection: Sample protection under abnormal conditions<\/li>\n\n\n\n
  6. Low\u2011level alarm for various reagents, cooling\u2011water shortage alarm and distilled\u2011water shortage alarm to prevent sample failure.<\/li>\n\n\n\n
  7. Operability<\/li>\n\n\n\n
  8. New\u2011generation chip and responsive touch\u2011screen for user\u2011friendly interface. Question\u2011answer operation enables operation without manual. Operation manual is stored inside chip for zero\u2011training requirement.<\/li>\n\n\n\n
  9. Two\u2011year maintenance\u2011free, three\u2011year free software upgrade<\/li>\n\n\n\n
  10. Automatic water\u2011saving function: Cooling water is switched on automatically only during distillation.<\/li>\n\n\n\n
  11. Kjeldahl nitrogen analyzer is essentially a distiller with simple structure but corrosive reagents. Xiamen Kelitai applies targeted pipes & materials for different gas and liquid circuits together with proprietary technology to realize two\u2011year maintenance\u2011free (warranty) for whole unit (except glass parts). The latest chip supports remote equipment status diagnosis to assist user maintenance, and provides 3\u2011year free software upgrade.<\/li>\n<\/ol>\n\n\n\n
