TS-NA818  Automatic nitrogen analyzer,with the classic Kjeldahl nitrogen method for the working principle, safe, fast, accurate, low consumption, human.There are many modes of operation:Automatic mode:Distillation titration fully automated, without personnel duty, automatic calculation of protein analysis results;Manual mode:Add alkali, add acid, add distilled water, distillation can be individually controlled, can also be carried out at the same time;Automatic titration, manual titration can also be mixed operation.The difference is that you can set the user-approved color to the end point.Based on the conventional color sense sensing, the application of the company's color filter technology, coupled with adjustable jitter judgment function to make the end of the color to accurately determine.The color difference and the curve are displayed directly so that the user can see the instrument's decision process.And built-in flexible open titration debugging system,the user can be very convenient to set the titration parameters,fully demonstrate the 818 system logic capabilities.818 is suitable for users with high accuracy requirements for test results.
 
The main features:

1.   Use of international standards of the Kjeldahl method: concentrated sulfuric acid digestion, alkali distillation, boric acid, receiving, indicator titration;
2.   The use of continuous titration, can be unlimited titration, do not need to back and forth pumping reagent;
3.  The end point is adjustable: the user can set the user recognized color as an end point;
4.   Three-stage titration speed automatically intervene to ensure that is fast and accurate;
5.  Pretitration function: the pretitration of the known concentration samples can greatly increase the titration speed.
6.   Automatically remove waste and clean;
7.   Work: hand automatically together, a variety of manual functions;
8.   Display: 7-inch LCD ultra-fine color widescreen display;
9.   Control panel: touch type;
10. Dedicated reagent barrel, equipped with liquid alarm bit instructions;
11. Anti emergency: after power failure can continue to test, does not influence thetest results of current sample; avoid incidents caused sample scrap;
12. Splash proof pipe material: high performance strong acid and alkali resistantmaterial molding; good sealing performance, alkali resistant glass is strongerthan, long service life;
13. Automatic water-saving: automatic closed condensate water non distillation process;
