AC220 50/60HZ ST115C Automatic Kjeldahl Analyzer 1500W Measuring 0.1~200mgN

ST115C automatic kjeldahl analyzer

ST115C automatic kjeldahl analyzer adopts the international standard kjeldahl method to judge the color endpoint, which is widely applicable to the nitrogen content analysis of diversified samples (food, oil crops, feed, fertilizer, seeds, dairy products, beverages, soil, etc.). The instrument adopts four independent imported metering pumps to achieve efficient and accurate automatic liquid feeding.

Distillation, separation, condensation, titration calculation, results printing.

Automatic Kjeldahl Nitrogen Analyzer for Food Crops and Feeds

Product features

1. The instrument is made of ABS engineering plastics, waterproof, electric and anti-corrosion, acid and alkali resistant and high temperature resistant

2. All pipe systems adopt imported corrosion resistant pipes and pipe fittings to ensure that there is no leakage in the pipeline system of the instrument

3. 7.5-inch true color touch screen, Siemens CPU control platform, bilingual man-machine dialogue in Chinese and English, easy to understand and easy to operate.

4. The liquid supply method adopts the original anti-corrosion metering pump of Germany, with reliable and accurate performance

5. The built-in 110mm wide line printer can realize the printing and output function of measurement data

6, millions of batches of data storage, can be arbitrary query, print

7. High precision titration system, up to 0.5 uL/ step, accurate and reliable results

8. Unique program-controlled heating mode can reduce analysis time and improve work efficiency

9, intelligent cooling water control system, real-time monitoring of cooling water temperature, water pressure and flow

10. Heating system -- SSR heating control relay;

Silent operation, strong overload capacity.

11. Automatic cleaning titrating cup procedure -- to prevent the influence of non-neutral residual liquid in titrating cup on the low content and blank samples, so as to improve the accuracy and reliability of the system.

12. Automatic dilution function to prevent overreaction of strong acid and base -- before adding alkali, add an appropriate amount of distilled water to dilute the sample of strong acid to prevent the strong reaction of strong acid against strong base.

13. All-round security protection system:

(1)leakage protection: when there is leakage or the operator accidentally electric shock, the system will cut off the power supply to stop power supply, to ensure the safety of the operator;

(2), the interval type of adding alkali - the process of adding alkali is not an instant, but the interval type of adding, can appropriately reduce the acid, alkali too strong reaction.

()3Elimination tube vacancy protection -- the system does not work when the elimination tube is not put in.

(4) safety door absence protection -- when the safety door is not pulled down, the system does not heat, to ensure the safety of the distillation process operators.

(5) overtemperature and overpressure protection of the steam system -- to prevent the danger caused by excessively high pressure of the steam system.

(6) steam cylinder automatic water replenishment function -- when the steam generator is short of water or water level is insufficient, the system will automatically replenishment water to avoid dry burning.

(7)pre-add water mode -- before adding lye first add a certain amount of water, dilute the digestive tube in the concentrated sulfuric acid, can reduce acid, alkali violent reaction.

(8)safety mode - before adding alkali to the sample for proper heating, can prevent acid, alkali strong reaction.
