Fully automatic Kjeldahl nitrogen analyzer

Scope of application:

The fully automatic Kjeldahl nitrogen analyzer is used to detect nitrogen content or protein content in food, medicine, soil, chemical industry, agriculture, forestry, materials, environmental monitoring and other fields, and determine the cation exchange capacity.

Functional features:

1. Adopt the national standard Kjeldahl nitrogen determination method: concentrated sulfuric acid environment digestion sample, alkaline environment steam distillation, boric acid absorption, indicator titration endpoint color judgment method. And participate in the drafting of the national standard GB/T22923-2008 and the official JJF109-2012 "Nitrogen Determinator Calibration Specification";

2.☆Fully automatic reagent addition, fully automatic distillation titration, fully automatic waste discharge and cleaning of the titration cup, fully automatic calibration, fully automatic fault detection, fully automatic solution level monitoring, fully automatic calculation, data storage, test report generation;

3. The titration color can be automatically and manually calibrated. The titration endpoint determination uses a high-precision 16-bit three-primary color digital signal color sensor to collect color signals.

4.2.0μL high-precision titration system, professional integrated precision plunger. Ensure test accuracy and reliability of use.

5. Color LCD touch screen, optional Chinese and English operation interface, real-time monitoring and display of experimental process, conditions can be automatically saved;

6. Can store 1000 sets of complete test data;

7. Fully automatic fault detection and prompts: safety door, digestion tube in place monitoring and prompts, reagent level monitoring and prompts, steam furnace level and temperature detection and prompts;

8. Adopt mature and stable steam generator technology, automatic preheating, water replenishment, automatic control of steam pressure, automatic dry burning prevention, automatic cleaning;

9. Automatically control steam pressure within a safe range, away from the danger of steam overpressure;

10. Double distillation mode, manual and automatic switching at will;

11.☆ Alkali pump adopts highly reliable polytetrafluoroethylene Ethylene bellows pump, special anti-corrosion, particle clogging resistance, stable liquid addition, no danger of negative pressure suction;

12. Water-saving design, cooling water flow rate 1.5L/min, cooling water is only turned on during the distillation process, cooling water flow rate is monitored in real time, low water pressure alarm is displayed, and water is automatically stopped;

13. The distillation system specially designed in accordance with the law of ammonia escape ensures a highly reliable test recovery rate;

14. Intelligent design of facilities around the digestive tract, transparent acrylic protective cover, completely isolates the danger;

15. The steam generator has multiple protections such as pressure sensor, temperature sensor, temperature protection switch, and water level double detection;

16. The instrument has self-test function and one-button reset.

17.☆Reagent barrel liquid level monitoring to ensure that there is no liquid shortage during the experiment.

18.☆Polymer material splash-proof bottle design.
