Fully automatical total kjeldahl nitrogen in wastewater experiment protein determination
Kjeldahl system for kjeldahl nitrogen determination includes Distillation, titration and result processing
An automatic device integrating distillation and titration functions designed based on classic Kjeldahl nitrogen determination method.
1. Complete microcomputer control
2. Self-inspecting function for all pump, valve and detector, easy trouble shooting via operating interface
3. Large LCD Touch Screen Panel
4. Colorimetric Titration device is meet International and national standard method
5. Compatible with φ42 digestion tube
6. Titration while distillation, enhance the efficiency rapidly.
7. User friendly design, color touch screen, easy for operating
8. PTFE Splash-proof device is anti-corrosion, longer life than glass material
9. Automatic waste discharge and cleaning ensure operator safety and save worktime.
10. External titration cup design gives operator real-time control of the whole test process.
11. Steam flow is controllable, satisfying different test requirements.
12. Regent barrel enjoys fluid absence warning function, ensuring smooth test going.
13. High-precision charging pump and titration ensure test results accuracy.
14. The temperature of distilled liquid is detected real time. If the temperature of distilled liquid is abnormal, to ensure the accuracy of experiment’s result, instrument will stop working.
15. Double distillation model is used to meet different experiments, to retard the speed of acid-base reaction.
16. Digestion tube fast drain function is used to avoid operator touch distilled hot reagents, protecting operators.
17. USB or RS485 interface is optional for PC connection.
