Domestic nitrogen analyzer

The DRK-K616 fully automatic Kjeldahl nitrogen analyzer is a fully automatic distillation and titration nitrogen measurement system designed based on the classic Kjeldahl nitrogen determination method. The core control system of DRK-K616, as well as the automated whole machine and refined components, have created the excellent quality of DRK-K616. The instrument can achieve automatic waste discharge and cleaning function of the digestive tract, easily completing the automatic waste discharge and cleaning work of the titration cup. The newly designed steam generation system can control the steam volume and real-time detect the temperature of the receiving liquid; The high-precision corrosion-resistant liquid pump micro controlled titration system ensures the accuracy of experimental results. Widely used in food processing, feed production, tobacco, animal husbandry, soil and fertilizer, environmental monitoring, medicine, agriculture, scientific research, teaching, quality supervision and other fields, for the determination of nitrogen or protein content.

Product Features:

1. Fully automatic distillation, titration, calculation, automatic emptying and cleaning functions provide safe and time-saving operations.

2. The steam flow rate is controllable, making the experiment more convenient and flexible.

3. The real-time monitor for the temperature of the distilled liquid automatically stops the operation of the instrument when the temperature of the distilled liquid is abnormal, ensuring the accuracy of the experimental results.

4. Featuring a dual distillation mode to meet different experimental requirements and mitigate the intensity of acid-base reactions.

5. The fast emptying function of the digestive tract prevents experimental personnel from coming into contact with distilled hot reagents and protects their safety.

6. High precision liquid addition pump and titration system ensure the accuracy of experimental results.

7. LCD touch color display screen, easy to operate, rich in information, allowing users to quickly master the use of the instrument.

8. The instrument is equipped with multiple sensors such as safety gates, digestive tubes, condensate flow rate, steam generators, etc., and all information is under control to ensure the safety of experimental and operational personnel.

9. A true fully automatic nitrogen analyzer: fully automatic alkali and acid addition, fully automatic distillation, fully automatic titration, fully automatic waste discharge, fully automatic cleaning, fully automatic digestion tube emptying, fully automatic fault detection, fully automatic solution level monitoring, fully automatic over temperature monitoring, fully automatic calculation of results.

10. Real time guarantee of experimental safety: using a metal steam generator, equipped with multiple safety monitoring devices such as safety doors in place, digestion tubes in place, and condensate flow rate, to ensure the safety of experiments and operators in real time.
