Aoda ZDDN-II Economic Automatic Kjeldahl nitrogen analyzer
The automatic Kjeldahl nitrogen analyzer ZDDN-II is a measuring instrument designed based on the principle of Kjeldahl nitrogen determination method.
The automatic Kjeldahl nitrogen analyzer ZDDN-II is mainly used for the determination of sample nitrogen content and protein content. It adopts microcomputer automatic control and can switch between manual and automatic modes. It has functions such as automatic distillation control, automatic water addition, automatic water level control, and automatic water stop.
The Kjeldahl nitrogen analyzer is suitable for analysis, teaching, and research in industries such as grain and oil testing, feed analysis, plant nutrient testing,
soil and fertilizer testing, environmental protection, medicine, and chemical engineering. It is mainly used to detect the content of ammonia nitrogen, protein nitrogen, and other substances in grains, food, dairy products, beverages, feed, soil, water, drugs, sediments, and chemicals.
1. The automatic Kjeldahl nitrogen analyzer adopts microcomputer for process control, including manual mode and automatic mode, which can be set and switched according to your needs;
In automatic mode, the entire process of adding boric acid, alkali, distillation, and ammonia absorption can be fully automated in one go. The volume of boric acid and alkali addition, as well as the time for distillation and absorption, can be set by oneself.
In manual mode, the three processes of adding boric acid, adding alkali, and distillation absorption can be manually operated separately. The volume and time can be controlled by oneself to meet the needs of professional users
2. Large screen LCD display, English menu, touch buttons, easy and convenient operation.
3. Automatic Kjeldahl nitrogen analyzer with automatic distillation control, automatic water addition, automatic water level control, and automatic water stop.
4. Various safety protections: digestive tract safety door device, steam generator water shortage alarm, water level detection fault alarm.
5. The maximum number of storable operating programs is 250.
6. The shell is made of specially sprayed steel plate, and the working area is equipped with ABS anti-corrosion panel, which is resistant to chemical reagent corrosion and mechanical damage on the surface, and is acid and alkali resistant.
7. Water level detection, low water level alarm, and automatic power-off in case of instrument control system failure.
8. The standard configuration does not include a digestion furnace, which is optional.
