SY-1069 Total Nitrogen Water Quality Online Detector

(1) Working principle: The measurement method of SY-1069 total nitrogen online water quality analyzer uses alkaline potassium persulfate to convert ammonia nitrogen, nitrite nitrogen, and most organic nitrides into nitrate under conditions of 120-140 degrees. After adding a certain amount of hydrochloric acid to eliminate interference, the absorbance of nitrate is measured at a wavelength of 220nm, and the interference of organic matter on this absorbance measurement is corrected at 275nm. The total nitrogen content is determined based on the quantitative relationship between the corrected absorbance and the total nitrogen content.

(2) The SY-1069 total nitrogen online water quality analyzer has the following basic functions:

-Can set, proofread, and display time, including year, month, day, hour, and minute;

-It has an alarm function for system abnormalities such as equipment power failure, instrument leakage, and inability to import samples into the reactor, and displays the fault content. At the same time, stop running until the system is restarted;

-After each measurement, the pre-treatment device, instrument pipelines, valves, and other components are automatically cleaned;

-Automatic protection for power and water outages, as well as automatic recovery for incoming and outgoing power;

-Regular cleaning and sampling functions;

-Touchscreen viewing is more intuitive and easier to operate.
