  • K1306
  • Sonnen

Technical Authority and Trustworthy


1. Comply with international / national standard, adopt national standard Kjeldahl method: digest sample in concentrated sulphuric acid environment, steam distillation in alkaline environment, boric acid absorption, indicator titration end-point color determinate method;

2. Sonnen is one of the drafters of China’s national standard GB/T22923-2008;

3. Sonnen is one of the drafters of the official standard JJF 109-2012 《Calibration Specification for Nitrogen Analyzer》;


Product Function


1. Adding alkali and/or acid, distilling and titrating, titration buret waste removing, discharging, calibrating, fault detecting, solution level monitoring, and             calculating can all be realized fully automatically.  

2.Titration color can be calibrated both automatically and manually. The titration endpoint is judged by the color signal collected by the high accurate 16-bit       3-primary-color digital signal color sensor.

3. 2.0μL high-precision titrating system and professional unibody precision-work plunger are the assurance of the determination accuracy and operation            reliability. 

4. The color LCD touch screen is equipped, with both English and Chinese operation interface available. The whole experiment procedure is real-time               monitored and shown on the screen, and the condition can be auto-saved.

5. Date Storage: As many as 1,000 sets of testing data can be fully stored.  

6. Not-in-position prompt of security door and digestion tube;

7. Mature and stable steam generator technology is applied, automatic preheating, water supplying, steam pressure controlling, dry burning prevention, and     cleaning can all be realized automatically. 

8. The steam pressure is automatically controlled within the safe range, thus danger caused by steam pressure is prevented.

9. Double distillation modes are designed, both manual and automatic models can be randomly switched.

10. Alkali pump adopts high-reliable PTEF bellows pump, which is anti-corrosion and anti-partical-plugging, stable during liquid adding, and free from the             danger cause by negative pressure suction. 

11. Water-saving Design: Real-time monitoring of the circulating cooling water flow rate, warning reminder whenever the water pressure is lower than it is             supposed to be.

12. Distilling system is specially designed in accordance with Ammonia escaping rule, which is an insurance of the stable high reliable recovery rate.

13. The digestive tube is specially designed to be surrounded with intelligentized facilities, and the transparent acrylic cover is equipped for total protection.

14. Steam generator is equipped with pressure sensor, temperature sensor, temperature protection switch, water level double detection, and other                     protections like these.
