SKD-1000 Automatic Kjeldahl Nitrogen Analyzer, Delay Time 0-1800s, SHANGHAI PEIOU ANALYSIS INSTRUMENT CO.,LTD (CAT#: STEM-AIAE-3377-LGZ)

The automatic Kjeldahl nitrogen analyzer (protein analyzer) is a set of automatic intelligent testing instruments designed according to the classical Kjeldahl nitrogen determination principle. SKD-1000 uses a new long-life design, high-end microcomputer intelligent control, LCD color touch screen operation, Chinese menu interface after dialogue operation, automatically completes acid addition, alkali addition, diluent addition, distillation, titration, cleaning, storage, printing, etc. A series of standardized processes, the titration is judged by the international standard color method (color sensor), the instrument is easy to operate, the data is accurate, and the performance is stable.

Use stable and reliable red, green, and blue primary colors to judge, and display three curves, standard acid titration, and protein (nitrogen) content in real time. Help users monitor distillation, calculation, and titration processes in real time, so that users can know what to do.
The small titration volume starts from 0.8μl, the high-precision intelligent titration system that automatically adjusts the minimum titration volume according to the standard acid concentration, and the professional Seiko plunger pump ensures the test accuracy and high reliability of use.
It has various alarm and prompt functions such as safety door detection, reagent liquid level detection, cooling water flow, automatic real-time detection of water pressure, etc.
It has real-time detection and control of the temperature of the still.
It has the function of real-time detection and prompting of whether the protective door is closed.
The manual and automatic dual modes can be switched at will, and the whole test process is displayed in real time, which can judge whether the ammonia gas is completely distilled, judge the correctness of the data, and avoid the outflow of wrong data.
The distiller adopts double liquid level control (double insurance), and a mathematical model is used to find that the distillation cup enters the dry burning state, so as to prevent the still burning cup from being dry.
With condensate water cut-off sample protection function.
The condensing pipe adopts own technology.
Interstitial alkali addition ensures that the acid-base reaction is in a controllable state and avoids the violent reaction of acid and alkali in the absence of steam to generate heat and cause ammonia gas to escape.
Adjustable distillation power: ensure good recovery of low concentration samples.
Automatic acid addition, automatic base addition, automatic diluent addition, automatic distillation, titration (distillation and titration are carried out at the same time), automatic saving, automatic printing, and calculation results.
The whole instrument uses anti-corrosion, corrosion-resistant and long-life ABS engineering plastics to ensure that the instrument is insulated and does not rust.
The internal pipeline of the instrument adopts self-developed anti-corrosion pipeline, which is guaranteed for 3 years.
All kinds of reagents are metered by liquid pump and measured in ml.
Titration and distillation are carried out at the same time to neutralize the evaporated ammonia gas, avoid the escape of ammonia gas as much as possible, and reduce the detection time at the same time.
True uninterrupted distillation: constant steam, uninterrupted steam during make-up time. To ensure the smooth evaporation of ammonia.
The external cuvette is not affected by the external light source, which effectively improves the anti-interference ability.
Data and detection conditions are traceable.
Optional: The balance data is automatically input, the detection data is wirelessly transmitted to the computer, and the software can store the data unlimitedly.
Digestive duct emptying function.
When the instrument is in standby state, the cooling water valve is automatically closed.
