NK1100F automatic Kjeldahl nitrogen analyzer is an automatic equipment integrating distillation and titration functions based on the classic Kjeldahl nitrogen determination method. Equipped with the latest core control system, powerful automation and high-quality components, it can easily realize automatic waste and cleaning of digestion tubes and titration cups, control steam supply, and detect condensation temperature in real time. The high-precision oil charge pump and titration system ensure the accuracy of the test results, and the multiple liquid level detection makes the test process smooth. Complete microcomputer control Automatic completion of distillation, titration,calculation, printing, waste discharge and multiple protections, i.e.failure self-detection,hints of condensed water shortage, displacement of safety door and digestion tube and so on.   Large LCD Touch Screen Panel Large LCD touch screen gives visual operation and abundant information,enabling user to have a good command of it.   Performance advantage Compatible with φ42 digestion tube Titration while distillation, enhance the efficiency rapidly. User friendly design, color touch screen, easy for operating Faster ARM system, faster operating rate Digester model SH220F and SH420F is matching K1100F, with φ42 digestion tube   Characteristics: Automatic waste discharge and cleaning ensure operator safety and save worktime. External titration cup design gives operator real-time control of the whole test process. Steam flow is controllable, satisfying different test requirements. Regent barrel enjoys fluid absence warning function, ensuring smooth test going. High-precision charging pump and titration ensure test results accuracy. 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. Double distillation model is used to meet different experiments, to retard the speed of acid-base reaction. Digestion tube fast drain function is used to avoid operator touch distilled hot reagents, protecting operators. USB or RS485 interface is optional for PC connection.
