Product Description

Automatic Kjeldahl nitrogen analyzer
 

Model

FX-K57

Long life design, 32-bit microcomputer intelligent control, LCD color touch screen operation, Chinese menu interface to complete human-machine dialogue operation. The instrument judges the end point of the acid-base equilibrium of the reaction cup through the changes in the states of the red, green, and blue primary colors, ensuring stability and anti-interference. Can prompt to determine whether ammonia is distilled. The instrument automatically cleans and calibrates when turned on, eliminating the need for manual calibration and avoiding human inconsistency. Adopting patented technology (which can eliminate errors caused by long time intervals in continuous detection).
 

Features

1. Provide prompts on whether ammonia is distilled, whether the titration endpoint is at the acid-base equilibrium point, and whether the data is correct.

2. It has independent sample and quality control sample storage areas, and quality control samples are automatically generated into quality control maps.
3. It is possible to search for historical samples, quality control data, detection status, and whether ammonia gas is distilled as a reminder. With 100 samples per day, 250 days per year, it can store data for 8 years.
4. Wide application of standard acid, which can use 0.01-0.4mol/L standard acid, greatly expanding the detection range. Small titration volume 0.8 μ l. The instrument automatically adjusts the small titration volume based on the standard acid concentration.
5. The standard acid drop is quantified from 0ml-60ml, which is not limited by the volume of burette.
6. Equipped with various safety door detection, reagent level detection, digestion tube in place detection, automatic discharge of waste liquid from digestion tubes and reaction cups, automatic real-time detection of cooling water flow and water pressure, and automatic shutdown of condensate water when the instrument is waiting.
7. It has real-time temperature detection and control for the distillation cup;
8. Manual and automatic dual mode, convenient for special sample detection.
9. Intermittent alkali addition ensures that the acid-base reaction is in a controllable state, avoiding the intense acid-base reaction generating heat and causing ammonia gas to escape in the absence of steam.
10. Adjustable distillation power: Distillation within the 0-power range, meeting the special testing requirements of users.
11. The internal connecting pipelines of the instrument are customized by Hergren and are free of replacement for 3 years.
12. All kinds of reagents are measured and added in ml using a pressure free pump, which is safe.
13. Titration and distillation should be carried out simultaneously to avoid the problem of excessive titration.
14. The reaction cup is external and not affected by external light sources.
15. The data and detection conditions are traceable and can store unlimited pieces of data, meeting the requirements for data storage within the effective life of the instrument. The USB interface can be connected to a computer for further data processing.
16. For each quality control data storage, you can choose to print quality control charts, samples, and quality control data.
17. Connect the balance and automatically input the sample weight.
