a brief introdction

SKD2000 Automatic Kjeldahl Analyzer is designed primarily for Kjeldahl analysis, which is widely applied to the test of Protein/Nitrogen content in grain and oils, drink, fodder, soil, chemical fertillzer, pharmacy and residuals as well as the test of ammonium salt, volatile fatty acid or alkali in chemical products.


SKD-2000 Automatic Kjeldahl Analyzer  Detailed description of

Brand new long-service-life design, advanced computer intelligent control, colored liquid crystal touch screen operation, and Chinese menu-driven interface with man-machine conversation functionality are integrated in the design of SKD-2000. It is capable of automatically accomplishing a series of standard processes including the input of sample’s weight, adding acid, alkali and diluents, distillation, titration and printing. Replacing traditional complex potentiometry and simplex colorimetry, titration judged by international standard color method is employed, which guarantees the accuracy, performance and operation of the instrument. It has several proprietary intellectual property rights and patents and some technologies initiate in China and have reached advanced level internationally.

Features

The unmatched accuracy judged by coloring titration of three base colors is displayed by three real-time curves, titration of standard acid and quantity of protein, which help users to monitor the process of distillation, calculation and titration, replacing traditional poteneiometry and simplex colorimetry.

Patented microscale pump replaces the syringe and plunger pump for titration, which ensures the stability of long-time titrating(Injection pump works for a long time would ruin the plastic plunger easily)

Alarming system like the real-time monitoring of safety door, reagent levels, cooling water, water level and over-pressure is employed. Condenser water cut-off sample protection and high efficiency condenser pipe has gained patent.

Real-time monitoring the distillation cup is operated.

Safety door is designed for user protection.

Touch sensitive color display, manual and auto operation models switchable and real-time tracking of the whole process are applied.

Double sensor monitors in the steam generator eliminates the fault of heating anhydrously.

Condenser pipe with patent number: 201020689328.6

Intermittent alkali addition controls the exothermic reaction between alkali and acid during distillation and avoids the effusion of ammonia.

Variable distillation power ensures the recycling rate of the low concentration samples.

Automatic addition of acid, alkali and diluents; distill, titrate(distillation and titration happen at the same time), store, print and calculate automatically.

High-quality ABS shell will never rust and guarantee the ability of insulation and acid-alkali resistance.

The inner tube is made of corrosion-free material and alkali/acid resistance plastics, whose warranty period is 3 years.

Addition of all kinds of reagents is through liquid pump.

Distillation and titration are operated at the same time, which neutralizes the distilled ammonia and avoids the effusion of ammonia as well as the testing time.

Ceaselessly distillation even when replenishing water ensures the constant output of steam and the distillation of ammonia.

Reaction bottle is visible.

Number 201110008392.2 patent is employed to protect the samples from damage.

An efficient condenser pipe is used for the azotometer and its patent number: 201020689328.6

Adhering to the concept of " Never Rust", our products have been recognized by domestic and overseas markets.
