Overview
The TN online total nitrogen automatic analyzer uses potassium persulfate to oxidize the digestion solution and water samples under high temperature and high pressure. Various nitrogen-containing compounds in the water samples are converted into nitrates through potassium persulfate oxidation and digestion. Under acidic conditions, the nitrate complex reacts with the developer, and finally the color is proportional to the nitrogen content in the sample according to the depth of the color, so as to obtain the total ......
Product Details
Details
Performance characteristics:
1. Select valve components: select reagent sampling sequence, flexible and diverse channels, variable functions, easy maintenance and long life.
2. With printing function, it can be connected to a printer (optional) to print the measured data in time.
3. It adopts 7-inch touch screen and simple operation interface, which can make it easy for users to learn, operate and maintain.
4. The large data storage capacity realizes the preservation of historical data of no less than 5 years (measurement interval is 1 time/1h), which greatly meets the needs of customers.
5. Automatic leakage alarm function. When reagent leakage occurs, the instrument will automatically alarm to remind the user to perform maintenance.
6. Quantitative use of light signal recognition function to ensure high accuracy of quantification.
7. The maintenance of chemical reagents is simple and convenient, and the reagents are replaced once a month, which greatly reduces the user's maintenance workload.
8. U disk one-key upgrade, software update easier.
