Nitrogen analyzer

Detailed introduction:

HGK-55 Fully Automatic KjeldahlNitrogen analyzerIt is an automatic intelligent detection instrument designed based on the classic Kjeldahl nitrogen determination principle. It is widely used to detect the content of ammonia, nitrogen, and protein nitrogen in grain, oil, food, dairy products, beverages, feed, soil, fertilizers, drugs, and some chemical products. It is an important chemical analysis instrument for product quality testing.

HGK-55 Fully Automatic KjeldahlNitrogen analyzerUsing a brand new long-life design, 32-bit microcomputer intelligent control, LCD color touch screen operation, Chinese menu interface for human-machine dialogue operation, automatic completion of a series of processes such as adding acid, alkali, diluent, distillation, titration, cleaning, storage, printing, etc. Titration is determined using international standard color method, replacing traditional complex electrode potential method and single wavelength photoelectric colorimetric method. This instrument is easy to operate, accurate in data, stable in performance, and some technologies and structures have reached international standards. The instrument determines the endpoint by observing the changes in the states of the three primary colors, red, green, and blue. This technology is known for its stability and anti-interference capabilities.

Product Features:

Starting from a small titration volume of 0.8 μ l, the instrument automatically adjusts the small titration volume based on the standard acid concentration.

2. The standard acid droplet quantification ranges from 0ml to 60ml, without being limited by the volume of the burette.

3. It has various safety door detection, reagent level detection, digestive tube in place detection, automatic discharge of digestive tube and reaction cup waste liquid, automatic real-time detection of cooling water flow and pressure, and automatic shutdown of condensate water when the instrument is waiting.

4. It has real-time temperature detection and control for distillation cups;

5. Manual and automatic dual mode, convenient for special sample detection.

6. Intermittent alkali addition ensures that the acid-base reaction is in a controllable state and avoids the heat generated by the violent acid-base reaction in the absence of steam, which can cause ammonia gas to escape.

7. Adjustable distillation power: Distillation is carried out within the power range of 0-100% to meet the special testing requirements of users.

8. The internal connecting pipelines of the instrument use pipelines with specific requirements and are free of replacement for 3 years.

9. All reagents are metered in milliliters using a liquid pump.

10. Titration and distillation are carried out simultaneously.

11. The reaction cup is external and not affected by external light sources.

12. The data and detection conditions can be traced back, and unlimited data can be stored, which can meet the data storage requirements within the effective life of the instrument. The USB interface can also output data.

13. Each time the quality control data is stored, and the quality control chart can be printed.
