Basic Info

Model No.: KN680

Product Description

Product Description

Product Application

KN680 Kjeldahl apparatus use the industry-leading 16 degrees trichromatic color sensors, precision endpoint to determine the fuzzy search technology, combined with advanced titration system structure to ensure more accurate titration; unique anti-alkali pump crystal technology, the complete elimination of crystallization of the alkali pump problems and improve the reliability of the instrument; modular design and multiple security, greatly ensure the stability, reliability, accuracy of the results to ensure the safety of operating personnel and equipment. Humanized operation interface, easy to use; complete experimental configuration system, to meet various test requirements; powerful self-learning function, to facilitate users to create their own test database; end users to fine-tune the technology and end color of color learning function can not only accurately to adapt to a variety of testing situations, the more users experience the technology of human nature.

Main Features

1) fully automated testing process: adding acid, alkali, distillation, titration, calculate and print out the results of automatic completion, without human intervention.

2)the original method of sample dilution and processing base, according to the user arbitrary set of different samples, the sample maximum to prevent the occurrence of explosive boiling phenomena and improve the measurement accuracy.

3) the original anti-crystallization of alkali pump, the complete elimination of crystalline alkali pump problems, to maximize the reliability of the instrument.

4) the steam flow can be automatically adjusted to achieve a better effect distillation to ensure the accuracy of the experiment.

5) dual mode of titration, the titration of the combined thickness will ensure a high degree of accuracy of the results.

6)the end users to fine-tune the technology and end color of color learning function, to ensure accurate test of adaptability, more human care.

7)automatic emptying digestive tract: the sample after distillation of the sample tube instrument automatically emptying the residual waste. Titration cup automatic scheduling of waste and cleaning

8)Built-in multiple safety protection: digestive tract in office testing, security doors, condensation water test, the steam generator overheating, overvoltage protection, liquid level detection, such as multiple intelligent protection to ensure the safety of equipment and operators

9)all lines and action components using anti-corrosion materials, precision build.

10)using a large touch screen LCD, with the class of easy to use Windows user interface.

11)a powerful experimental system and self-learning function configured to meet the requirements of various experiments.

Scope of application

 KN680 Kjeldahl instrument widely used in food processing, grain, feed, water, soil, pharmaceutical, tobacco, livestock, soil fertility, environmental monitoring, medicine, agriculture, research, teaching, quality control and other fields, the nitrogen or protein content determination. Can also be used for ammonium, volatile fatty acid / alkali and other testing.
