TN (total nitrogen) Online Analyzer, TN (total nitrogen) Online Meter, Water Analyzer, Sewage Water Treatment, Waste Water Treatment(spectrum detection method)
Product Principle( spectral detection method; Need to customize)：
In the 125℃ alkaline medium, use the potassium persulfate as oxidant, which can not only convert the ammonia nitrogen and nitrite nitrogen in the water into nitrate, but also convert most of the organic nitrogen into nitrate; then, measure the absorbance of total nitrogen in water with spectrograph at 220nm and 270nm.
① Adopt the new photoelectric quantitative technology, which is not affected by the high chroma, many suspended solids, lots of bubbles and other interference factors, thus ensuring high reliability and precision as well as strong anti-interference ability;
② Be characterized by high detection accuracy, low lower limit of measurement and small long-term drift amount of instrument;
③ Be featured with functions of self-test with one key and self-diagnosis;
④ Adopt the single-channel high-integration valve set, which ensures simple and quick maintenance and cleaning;
⑤ Be configured with 24-hour networking function, thus monitoring the running state of instruments at anytime and anywhere;
⑥ Be featured with functions of alarm, quality control and reverse control;
⑦ Be characterized by functions of automatic cleaning and automatic calibration;
⑧ Be featured with functions of hourly measurement, interval measurement and externally controlled measurement;
⑨ Be able to work automatically after power down and recovery;
⑩ Be featured with automatic prompt and automatic reset in case of fault and lack of reagent (sample);
⑪ Have the function of fault recording;
⑫ Can save more than 3 years of historical data.
⑬ Meet the requirement for the separate discharge of cleaning liquid and waste liquid.
