Automatic Kjeldahl nitrogen analyzer

Scope of application:

Automatic Kjeldahl nitrogen analyzer is used to detect nitrogen content or protein content and cation exchange capacity in the fields of food, medicine, soil, chemical industry, agriculture, forestry, materials, environmental monitoring, etc.

Functional features:

1. Adopt 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 participated in the drafting of national standard GB/T22923-2008 and official JJF109-2012 "Nitrogen Determinator Calibration Specification";

2. ☆ Automatically add dilution water, reagents (alkali solution and absorption liquid), distillation, equipped with calculation software, the calculation results are convenient and fast;

3. Color LCD touch screen, distillation time and reagent addition are set through the screen, and the conditions can be automatically saved;

4. Water-saving design, circulating water flow ≥1.5L/min only open circulating water during the distillation process, Real-time monitoring of cooling circulation water flow, low water pressure alarm display, automatic termination of operation prompt when water is cut off;

5. Safety door in place, digestion tube in place, steam boiler liquid level, steam boiler temperature, cooling water temperature monitoring and prompting;

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

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

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

9.☆ Adopt highly reliable polytetrafluoroethylene bellows pump, special anti-corrosion, particle clogging resistance, stable liquid addition, negative pressure suction without danger;

10.☆ Adopt ABS engineering plastic panel, corrosion-resistant, waterproof, and anti-electric;

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

12. Intelligent design of facilities around the digestion tube, transparent acrylic protective cover, completely isolate the danger;

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

14. The instrument has a self-check function, which can detect whether each function is normal.
