Notice on the holiday arrangement of Dragon Boat Festival in 2020! Dear customer: the Dragon Boat Festival is coming. According to the spirit of the notice of the general office of the State Council and the company's welfare policy, now our company is scheduled to take a vacation from June 25 (Thursday) to 27 (Saturday) 2020, a total of 3 days, and go to work normally on June 28 (Sunday).
COD analyzer is a kind of chemical oxygen demand analyzer. The COD measurements value will vary with the measuring of reducing substances in water samples and its measuring methods. At present, the most commonly used COD measuring methods are closed digestion Colorimetry method(tube test), (vessel test), (prefabricated tube test). The closed digestion colorimetry is also the instrument principle of COD rapid analyzer.
The determination of COD, ammonia nitrogen, total phosphorus and total nitrogen are all developed according to the documents issued by the State Administration of protection, and the results are accurate and effective. Closed digestion colorimetry is used for COD, Nessler's Reagent Colorimetry for ammonia nitrogen, closed digestion colorimetry for total phosphorus and closed digestion ultraviolet spectrophotometry for total nitrogen measurements. The instrument is widely used in environmental testing, sewage treatment, scientific research institutions and colleges. So, how to operate the total phosphorus analyzer?
COD analyzer is a kind of chemical oxygen demand analyzer. The measuring principle is rapid catalytic method (chromium method). With the application of cold light source display technology, the service life of the light source lamp is up to 100000 hours, and the switching of the measuring parameter light path becomes automatic from manual, eliminating the error factor of human rotation. In the laboratory and field, the COD of sewage can be measured quickly and accurately. It is the necessary experimental equipment for environmental monitoring station, environmental engineering technicians and enterprise laboratory. So, what are the using methods of COD Analyzer?
