TCd (total cadmium) Online Analyzer, TCd (total cadmium) Online Meter, Water Analyzer, Sewage Water Treatment, Waste Water Treatment
Product Overview：
Toxicity of metal Cd is low, but high of Cd compounds. Cd poisoning in human body is mainly caused by the polluted water, food and air, which absorbed by the digestive tract and the respiratory. Cd affects the health of the body slowly. It’s latency can be up to 10~30 years. The Cd, enter into human body and warm-blooded animals, mainly accumulates in the liver, the kidney, the pancreas, the thyroid and the bone. Then the Cd make the kidney and other organs diseases occurred and affects the normal activities of human.
This analyzer can automatic continuous work for long-term in an unattended manner. And it is widely used in industrial pollution discharge wastewater, industrial process wastewater, industrial wastewater treatment plants, municipal wastewater treatment plants and so on. Depending on the complexity at the scene, for ensure reliable and accurate testing, can choose different pre-treatment system.
Product Principle：
After the water sample is digested, cadmium ions reacts with 6-bromobenzothiazole azonaphthol in alkaline solution to form a kind of red complex, which is dissolved in trichloromethane, and compared with the standard series. Then, the absorbance is measured at the specific wavelength, thus calculating the concentration of cadmium.
Product Characteristics：
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;
